I'm still pondering the 'an ex was a Mormon'....I thought that a)they weren't supposed to 'date' outside of their religion and b)remain virginal....
I didn't vote on any; Richard Nixon was a Quaker-we see how much that background influenced him
Reagan was married, divorced, remarried-that didn't hinder his conservative moralistic views; Kennedy was a devout Catholic, but his progressiveness and 'amoralistic' private life belied that.
Of all the choices, I would probably not vote for a Jewish candidate simply based on our precarious standings with the Middle East. Any other religious background can swing from the 'eh' to the devout, but say "jewish" and it's all up for grabs.
