Well, I agree about the GOP, but Mitt is not a Democrat.
He's a manager. Like Dukakis, like Carter, like Bob Dole he doesn't GET the whole political thing. He thinks it's stupid.
His game plan, which works great for VC and for major complex projects, is to get all the experts in a room, Delphi them to death, and drag a plan out of them - and announce to the people that the experts have spoken.
There are domains where this is good - making tons of money is one of them - but national leadership is something different, something he has (I think) no clue about.
But he's nice to children and dogs, at at Treasury I'm sure he would kick ass.
Just because Mitt didn't screw up all the contacts he got from his daddy's Rolodex doesn't make him eminently qualified. Personally, I think that Herman Cain is far more qualified to serve at Treasury or Commerce than Romney. His self-made man story isn't an myth.
Well, he's nice to children, anyway. Not sure about the dogs.
(Note: Just a little joke. I don't have much of an opinion about the "dog on the car roof" issue, but it was Leno fodder for a week or so back in '08.)
"Treasury" is fifth in line of succession to the presidency - way too close.
