As a confessional Lutheran pastor, I am as opposed to Mormonism as anyone. It is a false, made-up religion. It teaches wrongly about the person of Christ and the Trinity, thus putting it outside the bounds of Christianity. Mormonism will send people to hell.
That doesn't mean I won't vote for a Mormon, though, for political office. As long as the candidate does not use his office to advance the false teachings of Mormonism, I'm OK with it. Neither Gov. Romney nor his father, the previous Gov. Romney, from all I've read, ever used their political offices to try to establish Mormon religious distinctives.
Most all politicians I've ever voted for, unless they're confessional Lutherans, I do not agree with theologically. That doesn't mean they can't do a good job politically.

That is exactly what Mormonism does. Ask Bob Bennett who was told to vote against his conscience by his prophet. Ask the 13 US senators and congressmen who went to Switzerland to ask for an exemption ONLY for the LDS church to their new missionary laws. I can document both of those.
As a former Mormon, I know exactly how their tentacles reach out and how an LDS POTUS will be used to promote their cult.
