Through unprecedented partnerships with both the Democratic and Republican National Conventions, we just debuted a video contest that will send one talented winner from each side of the aisle onto their candidate's campaign trail, and ultimately into their party's national convention in Denver or Minneapolis-St. Paul. The call to action is simple: submit a video explaining why you're a Democrat or Republican in 2008. The five most compelling and creative videos selected by each convention will be voted on by the YouTube community, who will determine the final winner.

Learn more by watching these videos from Republican Chairman Mike Duncan or Democratic Chairman Howard Dean.

These contests are a part of our larger partnership with the Democratic and Republican National Conventions. As the official providers for search and online video community, Google and YouTube are contributing a broad range of technology and services to help delegates, members of the media and interested citizens around the country to access convention events and information. And on YouTube, the two convention staffs have been busy posting videos to build buzz about the exciting events in Denver and Minneapolis-St. Paul this summer - like speeches from great moments in convention history.

So check out YouTube's Convention Headquarters and submit your video to the contest today. It's your chance to get involved in what promise to be two of the most exciting political events this summer.
