CBS Poll: Mike Huckabee Surging In Iowa

Romney Leads, Ex-Arkansas Governor In Second With 21 Percent; Top Three Democrats Deadlocked

(CBS) 
Meanwhile, on the Democratic side in Iowa, the contest appears also appears to going right down to the wire. None of the top three has firmed up their support yet - about half of those backing each candidate said they could change their minds before caucus night.

Despite that fluidity, there are some clear patterns that show how important it will be for each candidate to turn out certain groups of voters: Women have a strong preference for Clinton, while those under the age of 45 give Obama a double-digit lead. Obama and Clinton are nearly tied for support among first-time caucus-goers, but previous attendees give Edwards a narrow edge over Clinton.

The findings indicate that if older and established voters dominate turnout, the caucuses could be a two-way contest between Clinton and Edwards. If the Obama campaign succeeds in its bid to bring young voters and first-time caucus-goers out on Jan. 3, however, it could leave Iowa with a win and a crucial momentum boost headed into later contests. Doing so will be a challenge: Only a third of possible first-time attendees say they will "definitely" attend the caucuses, compared with six in 10 of previous attendees.

One factor in Obama's favor is that nearly two-thirds of the state's independent voters who plan on voting on Jan. 3 say they'll attend the Democratic caucus. Obama attracts the support of 37 percent of those voters, compared to only 17 percent for Edwards and 15 percent for Clinton.

The priorities of Iowans will also be crucial. Clinton is seen as the most electable in November 2008 by a wide margin. However, Obama is clearly seen as the most likely to bring about change in Washington and Edwards holds a strong edge on the question of who understands the problems of Iowans.

Edwards and Obama may also want to spend time making sure supporters of second-tier candidates see them favorably: Among those favoring other candidates besides them and Clinton, Edwards was the second choice of 30 percent, while Obama was close behind at 27 percent. A supporter of any candidate getting less than 15 percent support on the first count at a caucus is allowed to switch to another candidate or enter an "uncommitted" group.

As contentious as Iowa is, the next state on the campaign calendar, New Hampshire, is far less competitive. Among likely Democratic primary voters, Clinton has 37 percent support, putting her 15 points ahead of Obama. Among Republicans, Romney continues to dominate. He was backed by 34 percent in the poll, while John McCain and Giuliani both trailed at 16 percent. All other candidates were in single digits.

Clinton's support in the Granite State is solid. Though 52 percent of voters say they could change their mind, 62 percent of Clinton supporters "strongly favor" the New York senator and former first lady. As in Iowa, her experience is the top reason people are supporting her.

Many New Hampshire Republicans also have yet to make up their minds, even more so than Democrats. Among likely GOP primary voters, 66 percent said they hadn't made up their minds. Romney, unlike Clinton, has yet to solidify his support - only 31 percent of Romney backers said they had made up their mind. More than half of his supporters have reservations about him or are behind him because they dislike other candidates in the race. And the poll indicates Romney's religion could be a problem: more than one-in-four voters said they know someone who would not vote for a Mormon candidate.

CBS News and The New York Times conducted telephone interviews with 1273 likely caucus-goers in Iowa November 2-11, 2007 and 719 likely primary voters in New Hampshire November 9-12, 2007. The error due to sampling could be 4 points for Iowa Democratic caucus-goers, 5 points for Iowa Republican caucus-goers, and likely New Hampshire Democratic voters, and 6 points for likely Republican primary voters in New Hampshire.

In New Hampshire, sampling was done using standard RDD probability selection processes. In Iowa, the sample was drawn from three sources: the state of Iowa’s registered voter list (matched to phone numbers where possible), an RDD phone sample with numbers that matched numbers on the registered voter list eliminated (in order to sample phone numbers unavailable on the state list), and a small cell phone sample.

Results were weighted by probabilities of selection and by demographic characteristics to reflect the New Hampshire adult population and the Iowa registered voter list. To create the probable electorates for each state, registered voters were also weighted by their intention of voting, their attention to the campaign, and factors related to their past voting behavior. Likely caucus-goers in Iowa represent 17% of the registered voter population; likely voters in New Hampshire represent 59% of the state’s registered voter population.
