DES MOINES (CNN) - Just 48 hours before the Iowa caucuses, there are still enough undecided voters left to hand the race to any of the top candidates.
Democratic and Republican White House hopefuls are spending their days crisscrossing the state to visit rallies, house parties, restaurants - wherever voters can be found. And campaigns and independent groups working here are making aggressive outreach efforts through phone banks and canvassing.
Still, some Iowans just can’t seem to make up their minds. In the new CNN/Opinion Research Corporation Poll, 17 percent of likely Democratic caucus goers said they are have not yet decided who to vote for, and 11 percent said they were leaning but not definitely decided. More than a quarter of Republican caucus goers said they were still trying to decide, and 21 percent said they were leaning.
So the candidates and their operations are focused on shoring up the commitment of those supporters already in their camp, figuring out how to sway those still trying to decide – and gathering detailed information on individuals in both groups.
Iowa voters are notorious for wanting detailed information of their own: the campaigns distribute detailed position papers at events, and the candidates often answer voters' questions. John Edwards has gone a step further - setting up a special website where voters can submit questions they were not able to ask in person, which he is pledging to get them answered before Thursday night.
One woman attending an Edwards event Monday in Storm Lake said she never had attended a caucus before but said she was likely to do so this year. "I don't like politics," she said, but added that the former North Carolina senator might be able to "change things."
Many people attending Mitt Romney house parties in Ankeny and Clive Tuesday afternoon said they were going to attend a caucus this year for the first time, but had not yet firmly committed.
"I have a desire to see how the process and does work," Julie Donilson said. She said she is going to do more research on the positions of Romney and Mike Huckabee, between whom she is trying to decide. Her husband, Ron, said "it is just absolutely important that we show up and provide input. Both parties are wide open."
All of the campaigns are trying to find the last-minute message that will earn the support of voters like Donilson, and get these new supporters to the caucuses on Thursday.
