In the primaries 60%+ voted against Romney, and most of them still feel that way.
So, in an “undeluded by massive advertising state of mind” they can simply not support him and tell that to everyone.
That will easily get his polling numbers against Obama down in the 30’s and the GOP will suicide or change horses.
In Michigan 57 of our 83 counties voted for Santorum and Romney won the Obama stronghold that he can’t possibly win in November.
Romney ran for the nomination like a liberal.
