A familiar recipe
One vote is enough, as the old saying has it. And certainly, if Nick Clegg impresses his party and the country, that will be proved right again.
There is, though, another if - if Chris Huhne (whose campaign, let's not forget, came up with the insult 'Calamity Clegg') really does mean to work with the man who so narrowly defeated him.
Together with the newly-invigorated and popular Vince Cable, these three men could make a highly-effective troika. But the fact that 10,000 fewer Lib Dems voted in this leadership election, compared with the last one, demonstrates how much more they have to do.
Today, having first cast aside the popular Charles Kennedy, and then the experienced Menzies Campbell, the Lib Dems have somewhat tentatively picked someone unknown and inexperienced, but with bags of energy and charisma.
It's a recipe that recently worked for the Tories and, once before, for the Lib Dems - with Paddy Ashdown. The party is hoping desperately that it will work for Nick Clegg as well.
