Iowa became significant because it pushed Huckabee into the limelight...two months ago, did anyone think Huckabee had a chance to emerge as a top tier candidate for the GOP.
Iowa is also significant because Hillary took 3rd place.
Considering how much money the previous frontrunners pumped into Iowa, the results are surprising, and have set a new tone for this election.
Granted, Gulliani conceded Iowa, and is focusing his attention elsewhere...saving his war chest for more significant states, but I don't think he expected the Huckabee factor. McCain has gained some ground in recent weeks, but I don't think he has a chance for the nomination. If Romney takes NH, it could be a Romney versus Huckabee match-up for the rest of the primary season for the GOP.
Obama already had momentum, and Iowa will continue to shift the polls in his favor...especially after his victory speech last night, which was remarkable...his message of change is resonating, and drawing independents to the Democrats...which is what they will need to win the general election.
Hillary was losing steam going into Iowa, and I think last night's results will essentially kill her campaign. Her attempt to frame her candidacy as experience = change did not work...she has one option left, and that is a smear campaign against Obama.
Edwards is still in the fight given his taking second last night.
I personally love the fact that the annointed candidates...Guilliani and Hillary...are taking a beating.
