Alexis has a piece on the home page on Scott Walker as Iowa front-runner. Walker’s personal history, affect, and geographical proximity all line up well in the state (not to mention his record as governor). If he were to win there, he would be the first highly plausible candidate to win the caucuses since George W. Bush in 2000. When Mike Huckabee and Rick Santorum won in Iowa they had trouble following up, because their campaigns more or less consisted of the candidate and a car. Walker won’t have that problem. Of course, it’s still early. I think the candidate who will have the most direct interest in seeing him stumble is Ted Cruz, who needs Iowa and a unified conservative base. Walker in particular is a threat on both fronts.
