On 8 November, the US will decide who they want to be their next president.

Stories about the US election are all over the news, as Donald Trump and Hillary Clinton battle to become the country's next leader.

But there are a lot of complicated words and names being used.

Check out Newsround's US election dictionary below to find out what they all mean.

Blue state

This is a state where people will generally vote for the Democratic party - that is Hillary Clinton's party.


When people in the same political party go around the country and try to persuade people to vote for them, this is called campaigning. People who want to become president spend a lot of money doing this.

This is a building in Washington where part of the US government lives, called Congress. Congress is made up of two parts that you will find in the Capitol building - the Senate and House of Representatives.

A caucus is a type of meeting where members of a political party choose people, called delegates, to support the person they want to be the next president. People at the meeting openly show their support for the person they want, by talking or putting their hands up, like you might do in class. It is not done in secret, like a lot of voting.

These are held in around one in five of the US states (the others have different types of meetings called primaries) and take place in the first half of the year before an election.

A donkey is used as a symbol of the Democratic party.

It is thought this was first used during a presidential campaign in 1828, after the candidate Andrew Jackson used it on his posters because of a nickname his opponents gave him.

A cartoonist called Thomas Nast later used the animal to represent the Democrats and it became a popular symbol for the party by the end of the 19th century.

An elephant is used as a symbol of the Republican party.

It is thought it was first used like this by an Illinois newspaper during Abraham Lincoln's 1860 election campaign as a symbol of strength, although the exact reason is still debated.

It was then made popular after a man called Thomas Nast - who was a Republican - drew it in a cartoon in a magazine in 1874.

A primary is another type of meeting held within a state - like caucuses - at which people choose the person they want to represent their political party in the battle to be president.

The US is divided up into different areas called states, a bit like we have counties in the UK. There are 50 states in total, which come together to form the United States of America.

Each state has its own rules on some things, while others are decided by the law of the whole of the US, which everyone must follow. This is what is called a federal system.

People in each state vote for their own governor, who stays in the job for four years. Each state also chooses politicians who will work in the Senate and House of Representatives (look up 'Senate' and 'House of Representatives' in this dictionary).

Swing state

This is a state which often changes the party it supports from election to election.

This is why they are so important to people who want to be president, as they are open to be persuaded! Some states have already their minds made up and no campaigning is likely to change that.

For example, the Republican candidate is unlikely to spend much money campaigning in a state that is going to vote for the Democratic candidate.

Swing states include Florida, Ohio, Virginia, Colorado, North Carolina, and Nevada. It might also be called a battleground state or a purple state.

Barack Obama has been president for eight years, or two terms, so he is stepping down to let someone else be president now.
