That's what Jonathan calls Tim Pawlenty, who just dropped out of the race.
I'm pretty sure Pawlenty would've soldiered on a bit longer if it hadn't been for Perry's entry into the race. So far we have two clearly defined options -- unprincipled but competent centrist Mitt Romney, and crazy Michelle Bachman. Pawlenty was the candidate for people who for some reason were turned off by both, perhaps movement conservatives who seriously think about winning a general election. Now Perry emerges as the more exciting option for that constituency.
