I think the difference in the past 4 years among evangelicals is that they don't care about Mormonism when the alternative is a Muslim oriented marxist who hates America. It no longer was a big issue. Mitt sensed that as the campaign went on, and became more open about his faith, and I think it helped him when people saw how devout he was. Now, the election is over. The anti-Christian doctrines of the mormon church are unchanged and God willing we won't see another mormon as a POTUS candidate no matter how "devout" he seems. His devotion is to his sect, not to Jesus Christ.
