Romney for President

I have heard alot about Mitt Romney flip flopping on many issues. If this is so, why has he remained so faithful to the LDS Church. Wouldn't it have been easier for him to just say that it was a misstake. I was born Mormon but now I have found the way. Many of his supporters are non LDS so he could very well just say , I see their point and I want to follow the popular path. It's important to win South Carolina so I'm changing my religion. I know this is not going to happen. His religious belief is more important than winning the evangelical vote. Their vote is important to him however. He is going to represent the Mormon, the Catholic, the Protestant, the Jew and the Muslim ,even the agnostic. He will respect all beliefs. He will not force his religious belief on anyone else. I hope to stimlate some dialog . I'm just wondering why people feel he is going to change again to pro choice.
