Reagan was a democrat, but his positions genuinely evolved. In the 1950s he was speaking for GM all around the country about what he believed in(he wasn't running for office) and a woman pointed out to him that he sounded like a republican. he said well maybye i should switch registartions, and the woman happened to have a card with her so Reagan did. Ever since then reagan held the same set of core beleifs his entire career, from the 1960s all the way through his presidency. He embraced conservatism from the outset. There is a genuine evolution, and theres a fake one. Genuine is somebody like zell miller who after his grandchildren were born became pro life, he had no political benefit to do so, but he did.
What romney is doing is political opportunism. He is saying what people want to hear so he can be elected. He did it in MA, and now he's doing it because he wants to be the republican nominee. He only changed his position as he came closer to running for president, that's not a genuine change thats blatant opportunism.
I'm not questioning your conservative credentials, and don't you question mine. WHat i am pointing out is that your guy clearly lied, even the romney friendly site redstate pointed it out.
