One of the unique aspects of the 2009 MTV Video Music Awards is that the winner of the Moonman for Best New Artist will be decided entirely by fan voting. No matter who wins -- be it Drake, Kid Cudi, Lady Gaga, 3OH!3 or Asher Roth -- the victor will be the one who receives the most votes online. And this year, the online polls will remain open up until the moment that the presenter walks onto the Radio City Music Hall stage with the trophy in hand.

3OH!3 have taken this campaign very seriously. Saturday afternoon, they held a press conference that was streamed online via UStream, which allowed them to directly interact with fans and answer questions sent to them via Twitter. The whole event was set up like a real campaign event, with the Colorado flag (their home state) hanging behind them as they made their case for votes and provided a little insight about how they felt about the VMAs. The stunt may have paid off in a big way, as by the end of the press conference, "vote30h3" had become one of the top trending tags on Twitter.

So did 3OH!3 convince you to vote for them, or are they destined to fall to Roth, Cudi, Drake or Gaga (who even Sean and Nat admit is probably their stiffest competition)? You can keep voting all the way through the start of the show at the official voting site, and then tune in tomorrow night to see if the candidate you backed is the one doing a victory dance on the Radio City Music Hall stage!
