If Palin, Bachmann, Demint, or Cain were Mormon, that would not affect my vote even a little. I would vote for them in a heartbeat. The problem is that the leading LDS politicians are far left libs - Romney and Reid - and that gives their politicians a bad name.
People like you and I don’t want to vote for Romney because of his record. Add to this people who don’t trust Mormons and you have 0bama re-elected.
