It’s a moot point.
The people who would support Romney would never vote for Cain. The people who would support Cain would never vote for Romney.
Don’t know if you’re hinting at the mormon history of racism, but I will just come straight out and say it:
Obama will chew Romney up and spit him out, use that for all it’s worth, if the GOP is stupid enough to nominate him.
I know it’s not PC to say that, but it’s true. Next summer is going to be race baiting on steroids, and Romney is vulnerable. It needs to be considered.
Actually, I know at least 5 people who have switched from Romney to Cain. They were going with whoever FOX was pushing a while back, until they did their homework.
