Des Moines, Iowa – Walking around downtown, up and down Locust Street, I’m hearing the same thing from likely caucus-goers: “I don’t know,” “I’m undecided,” or “anybody could win this thing.” Over at New York, John Heilemann sums up the early, on-the-ground consensus:

But a first place finish by Santorum is by no means a done deal. The smart money around Des Moines is still betting that Romney will end up on top. Other wise guys (although their number is rapidly diminishing) contend that victory will be Ron Paul’s. And at least one self-styled genius still believes that Newt Gingrich could shock the world and pull off what this person calls “one of the greatest upsets in the history of the Iowa caucuses.” The genius in question is Gingrich, however, so please consume it with the requisite dump truck full of salt. As for me? I have no idea.

Later today, if you’re not in Iowa, you can watch the caucuses here. And if you want to hear my take from the capital, I’ll be on CNBC’s Kudlow Report at 7 p.m. Eastern.
