Iowa Caucus Ready to Roll

By  | 

The campaigning is almost over and the caucusing is about to start, and by the end of the evening we should know the winner of one of the tightest Iowa caucus races in history.

In the final hours, die-hard supporters are willing to bare anything and nearly everything for their candidate.

Congressman Richard Gephardt, Howard Dean and Senators John Kerry and John Edwards are in a dead heat, but in order to win, candidates will need more than strong supporters they will also need the backing of undecided voters.

Polls show 10 percent of voters are not committed to a single candidate and many others say they're willing to switch. After the caucus, the democrats move on to New Hampshire and another tight race.
