Who hates Mormons? Most people I know are indifferent to the religion.
Newsweek/Time/etc... would have cover stories on the Mormon Book of Abraham all on the same week. The NY Times would be running front page articles on the many historical inaccuracies in the book of Mormon (from horses to iron).
And they will all ask the same question: how can we trust the presidency to a guy that believes something that can be so easily disproven.
The fascists will use any angle they can, especially religion.
IMO a mormon is far better than someone like John Kerry. Who professes to have a mainstream religious belief but then says it doesn’t impact his policy decision.
How can you have a strong religious belief and not let it impact your policy decisions?
