Joe Klein is puzzled by Romney:

Romney remains a mystery to me: He's smart, he was a good governor, he's essentially a responsible moderate-conservative...but he has made an utter fool of himself flip-flopping and fudging--and taking wildly stupid positions (against the START treaty, for example) on issues about which he knows little or nothing. It almost seems a personality disorder.

Kevin Drum's answer:

Romney's a moderate conservative who figured out sometime between 2006 and 2008 that it was no longer possible for a moderate conservative to win the Republican nomination for president. The events of the past two years have made this even clearer than before, but Romney really, really wants to be president.
