First of all, Mitt is beating Obama by 2% in a national poll.
There are 10 current polls on the RCP average. Romney only leads in 2 of them. in one, Obama leads Romney by 5 points.
RealClearPolitics - President Obama vs. Republican Candidates
This is before Obama unleashes a billion dollars in negative ads letting us know about the "real" Mitt Romney.
Second, the fear of four more year of Obama outweighs the fear of electing a "creapy" Mormon. It's clear you haven't gotten to know many Mormons personally because is you did you wouldn't make such blanket statments about them.
Actually, had to spend 6 weeks with them at Ft. Lewis Washington in 1983 in an ROTC Advanced camp. Never before have I met such a bunch of two faced, back-stabbing scumbags in my life. Or since. Really learned to hate the bastards after that.
Third, it comes down to choice between Obama's hoplessness or a new direction. I don't think people want to assure another 4 years of Obama's nonsense when they have finally have a chnce at something better.
That assumes-
1) People are convinced Romney can make things better, when he's barely been able to convince Republicans fo that.
2) The economy stays like it is, when it is showing signs of getting better.
3) That Romney doesn't make more idiotic statments like "I like to be able to fire people", "I can't have illegals working here, I'm running for office, for Pete's Sake" and "Corporations are people, too, My friend."
