Can you cite a regulation for this. Hell, WJ> Bryan, certainly a man of God ran for president several times and came close once.
I think such a regulation would be an obvious rights violation. I distinctly remember the Catholic Church was the one that insisted this man not run for reelection.
No, you could be absolutely right. I was just pulling from what I've heard before. Maybe its the other way around and the Catholic Church won't allow clergy to run for office (just as it will not allow clergy to take up arms). I'm really not sure, to be honest.
