My answer...Barack Obama. He's out preforming Hillary in Iowa. Obama is gaining momentum and has been creeping up on Clinton Fast in Iowa polls, he's less than 2% points down, and he's drawing larger and larger crowds than Clinton. He's also from Neighboring Illinois which has strong ties with Iowa. A win in Iowa which is likely, will give Barack alot of momentum going into the rest of the primaries and would destroy Clinton's campaign momentum. Clinton has also "shot herself in the foot" with stories being uncovered about planted questions at debates and rallies so she doesn't have to answer questions she's weak on. It's also coming out that she has large supporters in charge of national polling companies who it appears are skewing polls. So Hillary looks like she's self-destructing due to graft. And Voters are starting to realize that Obama is more electable in the general election than is Hillary. So my bet is that Obama will win by a decent margin. Propelling him through the rest of the primaries to the nomination.
The loser in the General election.
