My knee jerk reaction would normally be that a Mormon is acceptable as a candidate. As a group, they're generally right on the issues I care about. Romney, however, blows it on this issue. I suspect that he's wrong elsewhere, but since he's fatally wrong here, I don't see the point in researching further.
I am especially impressed with his business and economic good sense. We have never had a man of his caliber in the presidency on such critically important matters.
