Election fever has gripped America as millions of people try to decide who should run for the President's job in November.
Super Tuesday is the biggest day in the campaign as 24 states all get to have their say on who they want to represent the Democrat and Republican parties.
Newsround's Laura went to Washington in America to find out what's going on.
"Remember how excited you all got about who was going to win X Factor, or Strictly Come Dancing this year? Well that's how worked up people here are about the elections for a new President.
It only happens every four years, so I'm really lucky to be here, reporting on it. And so far, it's been pretty exciting.
The first day we got here, our producer, Robert, our cameraman, Darryl and I went to the White House, which you'll recognise from loads of TV programmes and films - it's where the President lives.
While we were there, something really cool happened. All of a sudden, loads of secret agents and policemen turned up, and there was loads of noise, as three huge helicopters flew in, really low.
Two of them flew off to each side, but one went on to land on the White House lawn - it was the President's private chopper, and President Bush was on board, coming back from a trip!
The other two helicopters had been a diversion, so no-one would know which one he was on.
Although the actual elections don't happen until November, today is Super Tuesday, which is when millions of people choose who they want to be in the competition and who they don't.

Kids here are really excited about it. They think that whoever the new President is, they're going to have a big job to do - sorting out the war in Iraq and what's happening to the environment.
And that's why we're here.
Because, unlike the winner of X Factor, who gets to record a few songs, the person who wins this competition is going to end up being one of the most important people on the planet, with the power to change the world.
And that's a pretty big story."
