In anticipation of a national candidacy, David Broder examines Mitt Romney's tenure in Massachusetts.

UPDATE: I've had trouble getting online today and I've been meaning to post an update to this entry with a link to Joan Vennochi's column on Romney's evolution from a moderate, gay rights-friendly candidate for Mass governor to the present Christian Coalition-friendly presidential primary candidate. Jay also questions Romney's conservative credentials, noting:

Mitt's political positions have always depended heavily on what day, state and election it is at a given moment.

If he wins the primary in 08 and swings back to the center for the general, he can always recycle those positions that got him elected governor here.

UPDATE II: Andrew Sullivan weighs in on Romney, past, present and future.
