Some including myself would ask how any person with the power of reason and logic could believe much the catholic tradition/dogma. There are plenty of reasons to not vote for Mitt without being nasty about his faith.
There is nothing wrong with Christians making sure that the media does not advance the Mormon claim that they are

All Christian churches agree that Mormonism is it’s own unique religion, not a part of Christianity.
Yes there are but a Catholic is considered a member of a mainstream religion by a majority of Americans while many, many consider LDS a cult and won’t vote for a cult member.
