    Video caption: Super Tuesday: Bernie Sanders and Joe Biden trade punches

    We're wrapping our live coverage of Super Tuesday, now it is Wednesday on the US east coast.

    It's been a fascinating few hours in the race to decide which Democrat will take on Donald Trump in November's election.

    Here are the main takeaways:

    • even a few days ago, it looked like Bernie Sanders would run away with a big lead - this didn't happen, and he has won only three states so far;
    • after winning the vote in South Carolina on Saturday, former vice-president Joe Biden rebounded spectacularly - he won eight states;
    • Biden is now the front-runner - although we're still awaiting a crucial vote from California, that could help Sanders cut his lead;
    • Elizabeth Warren's campaign is all but over - she finished third in her own state, Massachusetts;
    • Michael Bloomberg won only American Samoa - but has done well in California and his campaign may not be finished

  2. Some known unknowns

    It's almost 01:30 here in Washington, and the picture is starting to become a little clearer. But here are a few things we don't know after Super Tuesday:

    • who has won Maine: Biden and Sanders are in a very close contest in the northeastern state
    • who has won Texas: Biden is building a lead over Sanders there though, in what might be a surprise result
    • who has won California: Associated Press says it will be Sanders, but it's not been officially declared yet (Sanders is leading Biden then Bloomberg)
    • how many of the crucial delegates will be awarded to each candidate - this won't be known until all the results are in (right now, Biden has 396 and Sanders 314 - a long way off the 1,991 needed to become the nominee)
    • who might be left in 24 hours: none of the under-performers - Elizabeth Warren, Michael Bloomberg and Tulsi Gabbard - dropped out on Tuesday, but that might change on Wednesday
  3. 'Now the hard work begins'

    Anthony Zurcher

    BBC North America reporter

    Joe Biden came into Super Tuesday hoping his momentum from a surprisingly big South Carolina win would translate into success in some of the state and allow him to keep within sight of Bernie Sanders in the delegate count. By that metric, his evening succeeded beyond his best expectations.

    Biden’s support among black voters, which was on display in South Carolina, was replicated across the south, in states like North Carolina, Virginia and Alabama, where he consistently won about 60%. It also helped offset Bernie Sanders's strength with Hispanic voters in Texas.

    Tuesday night was a celebration for Biden. Now the hard work begins. He is in for a state-by-state slog against Sanders that could stretch all the way to the Democratic National Convention in July. He’ll have to fundraise furiously and organise rapidly to make up for the Vermont senator’s advantages. Meanwhile, Republicans are going to start training their fire on him - again.

    If he ends up winning the nomination, after being left for dead just a few weeks ago, he will have earned it.

  4. The latest from California

    Voters wait for a voting center to open at Granada Park

    The state with the most at stake for the candidates is also the one that's most uncertain right now.

    California has a cool 415 delegates to dole out, but its size also means counting millions of votes could take quite a while - possibly weeks. About 30% of precincts have reported their results, and there are still thousands of mail-in votes to look at.

    In addition, local media report people are still waiting in long lines to cast their ballots even though polls closed nearly two hours ago.

    But the Associated Press has already called the state for Sanders. The New York Times has forecasted it's "pretty likely" Sanders who will take home the California haul.

    Bloomberg has also been doing well in California, overtaking Biden for the second-place spot.

    A reminder: you need 1,991 delegates total to win the Democratic nomination. Winning most delegates here will help, a lot, but it still won't make you the candidate.

  5. How close is the race now?

    Here are where things stand right now when it comes to the all-important delegates that candidates have won. (These are assigned according to how well candidates have performed):

    Some caveats: we don't have the results from the two biggest states Texas (where Joe Biden is building up a lead) or California (where Sanders is leading Bloomberg).

    This picture could change quite a lot over the coming hours, and Sanders could pull closer to the former vice-president.

  6. What will become of Bloomberg?

    Bloomberg

    Michael Bloomberg has said he will be re-evaluating his campaign following tonight's results. His only win was the US territory of American Samoa, but early polls in California and Texas have shown him in second and third place, respectively. Good results in these two states could get him closer to the front-runners.

    The BBC's North America reporter Anthony Zurcher says the former New York mayor could have an impact on this race depending on what he decides to do with his campaign machine.

    "Whether Michael Bloomberg decides to use this machine he's built up and turn it to say, support Joe Biden going forward, or whoever the Democratic nominee is in November, that's an open question," he says.

    "I think Joe Biden and his supporters have a very real interest in what Michael Bloomberg does from here on out...even if he doesn't have quite the same amount of support he did just a few days ago."

    If Bloomberg pours money into states like Michigan and Florida, for example, he could be drawing votes away from Biden.

  7. Biden's fake boss endorses him

    Comedy actor Keegan-Michael Key, who once portrayed former President Obama's "anger translator" in a sketch, is once again pretending to be Biden's old boss.

  8. It's very, very, very close in Texas

    Voters cast their ballot in the Democratic primary at a polling station in Houston, Texas,

    There's a lot at stake in the country's second-most populous state.

    Before Tuesday, it looked like Bernie Sanders would win there fairly comfortably, thanks partly to his support among Latino voters. That hasn't proven to be the case.

    With 61% of results in, Joe Biden has now edged into the lead. It's still very close though.

    There are 228 delegates available here - they may end up being shared fairly evenly between Sanders and Biden.

  9. An issue of tone?

    The BBC's Katty Kay points out, Biden's many wins could be thanks to issues of tone and civility.

    "It's not just this concept of civility, it's actually the words people use about each other," she says. "And Joe Biden, I think, appeals to people who might be looking for that in this country."

    Perhaps in particular to women, she adds, who are looking for the political landscape to be "less aggressive, less combative".

  10. Four takeaways from Super Tuesday

    It's no longer Super Tuesday here on the east coast of the US, it's now less-super Wednesday. As we continue to await results from California, Texas and Maine, here are some key takeaways from Tuesday's big vote.

    1) A new front-runner?

    Former vice-president Joe Biden's campaign was drying up until he won South Carolina on Saturday. That momentum has continued, with projected wins in eight states on Super Tuesday so far.

    2) Biden's Southern base comes out

    African-American voters were a big part of Biden's wins in the South. He won the majority of black voters in these states, proving his campaign's claim that he has a strong base among southern Democrats.

    3) But Bernie's still in

    Biden may have taken up his front-runner position once more, but Sanders could still unseat him. Sanders has been winning big among young voters and Latino voters. Latino voters, in particular, are a key demographic in the big-win states of California and Texas that are still up for grabs (it's still incredibly close between Sanders and Biden in Texas).

    4) A bad night for Bloomberg and Warren

    It has been a poor showing for both Michael Bloomberg (who has spent over $400m on his campaign) and Elizabeth Warren - who lost her home state (Massachusetts) and birth state (Oklahoma). In Massachusetts, women opted for Biden over her by a big margin.

  11. Why Biden Oklahoma win is so fascinating

    When it comes to Democrats and American politics, Oklahoma isn’t the first state you think of. Solidly Republican, the heartland state doesn’t feature in the Democratic story in presidential elections. But tonight, true-red Oklahoma is telling an interesting tale about the state of the Democratic race.

    In the 2016 Democratic primary race, Senator Bernie Sanders beat Hillary Clinton to win Oklahoma by 10 percentage points. Four years ago Sanders was seen as the anti-Clinton vote. He was the person Democrats rallied around if they didn’t want to hand the nomination to the establishment candidate.

    Tonight Oklahoma tells a different story. Joe Biden has beaten Bernie Sanders.

    In 2020, Joe Biden has become the anti-Sanders vote. For all those Democrats who don’t want a nominee from the left of the party, Biden is the guy. Not only is he the anti-Sanders candidate, he’s also the anti-Trump candidate. For Democratic voters for whom beating Trump is the number one goal, Biden, not Sanders looks like the most viable candidate.

  12. What Bloomberg's millions could have bought

    As rumours fly that Michael Bloomberg may drop out on Wednesday, let's take a look at what his nearly half billion dollars of personal campaign contributions could have bought.

    The billionaire ex-New York City mayor is the ninth richest man in the world, and has spent $464m on his campaign so far, according to federal campaign filings.

    For that money he could have:

    • Gifted approximately $9,280 cash to every single resident of American Samoa, the only place Bloomberg won on Super Tuesday
    • Bought almost two Tom Steyer campaigns. He was the other billionaire candidate in this race who dropped out on Saturday after spending $250m of his own pocket money
    • Purchased at least 11,600 Tesla electric cars
  13. Meanwhile,Trump wins

    Democrats aren't the only ones hosting primaries on Super Tuesday - Republicans have had their say too.

    Technically, the president isn't running uncontested for the Republican nomination.

    Former Massachusetts Governor Bill Weld is also on the ballot, but his candidacy is a long-shot, as a brief scroll through Trump's Twitter feed shows.

  14. Biden and Sanders trade blows

    Without calling each other out by name, both Bernie Sanders and Joe Biden have criticised each other.

    Watch as they trade political blows - over the Iraq War and general election electability - in their speeches tonight.

  15. The latest delegate count

    We're still waiting for projections for three states: massive Texas and California, as well as tiny Maine. And we're still awaiting the full results in almost every state.

    Remember, the aim for all candidates is to win 1,991 delegates, a different amount of which are awarded in each state, and according to how well each candidate has performed.

    With that target in mind, this is how many delegates each candidate has so far:

    • Joe Biden - 331
    • Bernie Sanders - 269
    • Elizabeth Warren - 18
    • Michael Bloomberg - 13
    • Tulsi Gabbard - 1

    We are a long, long way away from this being resolved.

  16. Sanders camp asks to keep California polls open

    The Bernie Sanders campaign is asking a judge to grant an emergency injunction to keep polling stations open in Los Angeles county due what they describe as long queues of waiting voters.

    Voters, their suit claims, have waited for up to four hours to vote at "multiple" voting locations.

    California has made strides to make voting as accessible as possible, according to the BBC's Sophie Long in Los Angeles.

    Some polling stations, which have been open since last week, allow for 24-hour voting. And across the city, public transit has been made free to allow voters to more easily get to their polling station.

  17. BreakingBiden wins Massachusetts

    Biden wins Massachusetts

    Biden is projected to win Massachusetts, which has 91 delegates.

    It's an embarrassing loss for Elizabeth Warren, one of the state's current US senators.

    Sanders was expected to do well, and he is projected to take second place, leaving Warren in a dismal third on home turf.

  18. Bloomberg rolls out Trump jokes

    It's been a bad night for the former mayor of New York. Michael Bloomberg has spent more than half a billion dollars of his own fortune and so far has only a win in American Samoa to show for it.

    Talking to supporters in Florida, however, he insisted he was still the candidate who could beat Donald Trump. And instead of despair in the face of defeat, he turned to humour (possibly with help from a teleprompter).

    We'll let you decide if Bloomberg did better with jokes than votes.

  19. Sanders gains a slight edge in California

    California is the prize tonight's Democratic presidential hopefuls all want to take home. The state has a massive 415 delegates up for grabs.

    Sanders currently has an edge in the state - as expected, given his success with Latino voters, who are a key California voter demographic. Early polls also show Sanders with a major lead over his rivals among young voters.

    The Associated Press has already called the state for Sanders, though polls closed just minutes ago.

  20. What's at stake in California?

    Over the day, we've been introducing you to young Democrats voting in 2020.

    The fourth is Paige Thielke, 17, from California. Although she was too young to vote in today’s primary, she will take part in November’s general election.

    Paige Thielke, 17, from California

    What’s at stake in this election?

    A lot, not just because it could bring about a change in government, but because the world is at a crossroads. Far-right, nationalistic political movements have been gaining popularity all around the world, and the climate crisis is only getting worse. Whoever becomes the president will have to deal with those issues, and after almost four years of Trump, it’s pretty clear how he would address those issues.

    Do you know who you are voting for? If not, what will decide your vote?

    While I understand the appeal of Bernie Sanders, who is by far the favorite candidate among many of my friends and fellow high school students, his reputation as being disliked by his fellow senators and the drastic nature of his policy proposals doesn’t make me feel like he could work across the aisle to get stuff done during his presidency.

    Because of that, my support tends to lean more towards moderates, even though the majority of them in the race aren’t ideal options.

    What should someone outside the US know about your state that makes it unique?

    California has the unique quality of being generally known across the world. But 40 million people live here (a bigger population than Canada), and there is no typical “Californian”. While the entertainment industry is certainly big, the Central Valley also produces 13% of all agricultural products in the US. It’s the most diverse state in the country, and is diverse not only in terms of race, but socioeconomic status, cultural experience, etc. So while the majority of voters do lean liberal, there are plenty of conservative areas as well.
