Newt Gingrich's personal baggage isn't as interesting (or damaging, I think) as his political baggage. He's been on all sides of as many issues as Mitt Romney. And if Romneycare is the one thing of Mitt's that I have the most trouble getting over, this is Newt's.
(Via Nick Gillespie of hit & run, who reminds those who have fogotten what an "opportunistic changeling" Gingrich is.)
