But when the dust settles and people like you pick our nominee, the real challenge will begin. This time, though, it won't be a debate of ideas with fellow Democrats. It will be against a Republican machine eager to redeem its losses in 2006, fighting to extend George Bush's policies for another four years.
We've all seen the way they run campaigns, so we have to be unified and ready. We know that the Republicans are going to come at us with every scam they think up to suppress the vote.
In the past, they've abused robocalls that hide their true identity, jammed the phones Democrats used for getting out the vote, and purged voters from the voter rolls. We need to be united in order to stop them.
Stand up and show our candidates, our opponents, and the country just how strong the Democratic Party is by joining me in a pledge to support the Democratic candidate for President in 2008 - no matter who wins. When we have a nominee, they'll know that thousands of Democrats from across the country are united - even if they may not have supported them in the primary.
Every one of the Republican front-runners - Rudy Giuliani, Mitt Romney, Mike Huckabee and John McCain - would continue President Bush's failed policies. America can't take a third Bush term, but that is all the Republicans offer.
They believe that President Bush's war in Iraq is a success. We believe that it's time to bring our troops home.
They support President Bush's pardon of White House Aide Scooter Libby. We believe in widespread ethics reform legislation to clean up the mess in Washington.
They agree with President Bush's veto of children's health insurance funding. We believe that no parent should have to worry about whether or not they can afford to take their children to a doctor.
No matter who you plan to vote for in the primary, there's one simple fact we can all agree on: Any one of our candidates will be better than four more years of failed Republican policies.
Pledge your support for the Democratic nominee in 2008, and then ask your friends to do the same. Everyone - from the nominee to the media to the Republicans - should know just how many people are behind our candidate this year.
Help us make a big statement:
