Huckabee putters into 2nd place Iowa polling, VP rumors abound

The title says it all, but to elaborate:

... partly by exploiting discontent among Christian conservatives with the Republican field, Huckabee, a witty former Arkansas governor, has powered into second place in polls in Iowa, 65 days before the state's crucial caucuses.

... In Iowa, an average by RealClearPolitics.com of recent polls has him in second place, on 15 percent and rising, behind former Massachusetts governor Mitt Romney on 29 percent.

... [he doesn't have much cash:] So, Huckabee is increasingly being mentioned as a possible vice presidential pick. - AFP
