Obama Widens Lead

The Des Moines Register's final Iowa poll before the caucuses finds Barack Obama increased his lead over Hillary Clinton and John Edwards.

Obama was the choice of 32 percent of likely Democratic caucusgoers, up from 28 percent in the Register's last poll in late November, while Clinton, a New York senator, held steady at 25 percent and Edwards, a former North Carolina senator, was virtually unchanged at 24 percent.

The poll reflects continued fluidity in the race even as the end of the yearlong campaign nears. Roughly a third of likely caucusgoers say they could be persuaded to choose someone else before Thursday evening. Six percent were undecided or uncommitted.

The poll also reveals a widening gap between the three-way contest for the lead and the remaining candidates. No other Democrat received support from more than 6 percent of likely caucusgoers.

Democratic caucusgoers are opting for change over experience:

Thirty percent of the poll's respondents said a candidate's ability to bring about change is the most important, followed by 27 percent who said their priority is choosing a candidate who will be the most successful in unifying the country.

Having the experience and competence to lead, which has been the crux of Clinton's closing argument, was seen as the most important to 18 percent of caucusgoers, with Clinton as the candidate most commonly rated best on this trait.

The poll was conducted December 27-30 and has a margin of error of plus or minus 3.5 percent.

Regardless of the poll results, I think Edwards will win the Democratic caucuses.
