No, it really is because he isn't a conservative. And I'm so tired of the Mittbots complaining those who against Romney are attacking Mormonism. Its trite, old, and completely untrue. If Romney were a conservative, I'd have no problem supporting him.
But he isn't.
The reason WE don't like him is that he's not conservative, but I'm talking about the country in general.
You are right, it has nothing to do with him being Mormon, it has to do with no charisma. He's like wallpaper. Good looking wallpaper, but flat and bland and unexciting. You can't be president in this country if you don't have that inexplicable something that draws people to you.
