Until death do you part... or until you find out she is a liberal. No wait, that's not it.
I admit, I am a religious nut of the Catholic variety. Marriage is a holy union to me. And nowhere does it say you may divorce over differences in politics.
I'm Cathloic too, but I guess I could be rigid and say that I have been voting for heretics all my life, with few exceptions.
Are you married?
