IMO you get hung up on non issues and miss what is important. I'm leaning Romney and if he adds Rubio he will be solid.
I have issue with romneycare and mormanism, and still need to watch his level of conviction on key issues. On the good side, he worked in a very liberal state and still had some success but seemed to be too willing to give in. He still has to prove himself to voters. However, he has stayed above the fray and has focused on the issues. He hears the number one issue is jobs and creates a detailed jobs plan, far beyond what this administration has done. He isn't a flash in the pan, gaffe ridden, polarizing force. If you look at the states that are must wins, he is the candidate. This is why the media is pushing Perry as the "obvious" winner.
