1) Only John Kerry and Al Gore have him beat on flip-flopping. Romney's the type to run pro-life in a GOP primary and once he gets the nomination he'd run pro-abortion to win the democrat votes and somehow explain that he never changed his mind or flip flopped.
If there was a democrat majority in Congress he would nominate liberal judges and by the time his re-election comes up in 2016 he will claim that he had to nominate liberal judges in order to get them passed through the liberal Congress. That's Romney.
The other problem about Romney is that he's too "in your face" as a candidate. He could easily lose it in a debate and earn sympathy for Obama. We don't need that to be happening.
Look, I think RomneyCare was a terrible idea, and if the guy was running for governor in my state based on implementing that, I wouldn't vote for him whether he had an (R) next to his name or not. But as long as both Gingrich and Romney oppose ObamaCare as national policy, then their position on it isn't a disqualifier for me, even if they are rightly disqualified for other reasons.
