Excellent point.
However, there is even more to it than that. Catholics supported JFK in a time when matters like abortion and homosexuality were non-issues. The only other Catholic nominee for president was John Kerry and he didn't get the majority of the Catholic vote.
Conservative Mormons on FR would do well to take a cue from Catholic FReepers, four years ago the Catholics on FR overwhelmingly rejected Rudy Giuliani.
I do not believe Mitt Romney can win this fall. But whether he wins or loses, those of us in the conservative movement have a major problem either way.
No candidate in American history has ever won without the enthusiastic support of his own party. Look at the primaries, the only states Romney won by large margins are liberal states that the GOP won't win anyway.
No doubt.
It is notable that in every conversation Romney Republicans must, in order to pass the initial laugh test, first admit that they can't stand the guy, that he has no morals, no principles, that he is a liar and a fake.
Right before they try to bludgeon you into supporting what they know you too detest.
