Lol, McCain at 3%
To be fair though McCain got only 4.71% in 2000 in Iowa, and then he was a highly serious candidate.
But that's because he was explicitly skipping Iowa and wasn't campaigning there. This time around, he *is* campaigning there....devoting more resources to Iowa than any other state save NH and SC. OTOH, he's skipping the straw poll, and it's possible that he and the other candidates skipping the straw poll are currently being hurt by negative local media attention associated with skipping the straw poll. And of course, folks like Brownback and Tancredo are currently making a big push in the state for the straw poll, so their numbers might be somewhat inflated because of that.
