Here's another place your argument falls down. If Romney now claimed it was a mistake, and it was wrong, fine. But he says he is PROUD of it? So even he isn't claiming he had to do it. He's claiming it was great. You want someone who is proud of communism as president? Even Obama said it was a bad law. The only one with the chutzpah to claim they are proud of it is Romney. If Obama is too scared to talk it up, what does that say about Romney. He is attacking his base and the independents.
Why can’t he be proud of it? That is what his constituents demanded.
