I lost this thread so I'll revive it even if no one agrees with me.
I should clarify that I don't mean to imply that McCain wouldn't win mormons and by a big margin too. Simply that fewer of them will turnout being disappointed in Romney not getting the nod. Of course, most mormon states are GOP strongholds. But Nevada could get a bit interesting. And I thought there were mormons in Colorado to a lesser extent? EDIT: no there isn't.
Still, the pattern would interest me if it were to happen, even if it changes few states.
