The problem with Romney is that he can't crack the 20%-25% level. The Republican base keeps looking for someone else. That's why you see Trump then Bachmann then Perry then Cain shoot up. They may eventually pick Romney, but its pretty clear the party isn't particularly enamored with him.
Is the electorate really excited about any of them ? Sure for a little while, but it go's away and then the new republican messiah comes along. Its still pretty early in the game to say who is or is not going to get there let alone win. .
But that's not really the case.
Last time, really far right, Toon Hall Conservatives HATED McCain with a passion, even though there wasn't a clear "conservative" alternative. Guiliani was too liberal, Romney wasn't trusted because of the Mormonism and the previous liberal record, Huckabee was too liberal on immigration and spending issues for some tastes. They had hopes for Fred Thompson, but he turned out to be a dud.
McCain had to pick Palin as a sop to the Right, and it backfired when she was found to be unprepared for the big leagues.
I think drawing attention to a candidates religion will be considered bad form and wont really matter. Obama got a pass for worshiping at the alter of a man who would have every white persons neck under his boot heel. And Al Sharpton got his fat jowls shaken for his comments on Romney.
I think that this election is any of the candidates to lose at this time
Obama got a pass because the Media wasn't willing to talk about the story that much. Hillary wasn't about to exploit it because she didn't want to antagonize blacks by attacking someone who had some reverence in that community. And McCain made the tactical judgment to not talk about the issue, and after the 2008 collapse, no one would have paid attention if he had.
Not familar with what Sharpton might have said about Romney.
Obama doesn't have to say anything about Romney's religion. The MSM will do that for him, AFTER Romney secures the nomination. Then we are going to get stories about MOrmonism so negative you'd think I was writing them.
