@Renaldo Dubois,
What do you think about Romney's health care problem? He supported a personal mandate. In Massachusetts he got a state wide personal mandate passed for which he proudly claimed credit. He is also on record in a couple of speeches in past years of supporting a national personal mandate which is the political key of Republican opposition to so-called "ObamaCare".
Romney has similar problems with gay rights and abortion. He took positions in the past on each of these issues that will be very hard for conservative voters to stomach if he can't find a way to spin his new found conservative position.
In Massachusetts, where he was governor, we called him "Multiple Choice Mitt" because on pretty much any issue you can find him taking whatever position he needs to take to help him in whatever election he is in at the time.
Romney is going to have problems getting the votes of the Republican core voter.
I think Romney would be the Republicans best chance against Obama. He is smooth and could probably woo a enough of the all important independent voters to have a shot combined with the people whose blind hatred of Obama would vote for anyone.
Fortunately, Romney is going to have big problems in the primary. Unfortunately I think he still has a decent shot.
