Question of the day!

Brownback Sorry for Mormon Comments

“Republican presidential hopeful Sam Brownback on Monday telephoned rival Mitt Romney to apologize for a campaign staffer’s e-mail criticizing the Mormon church.”

It seems I’m missing something but, I am unclear what’s Browback apologizing for here? Is he saying what someone believes is non-relevant? Or is he saying, “because I went from Protestant to Catholic, I don’t want matters of faith brought up.”

So I’m curious what you think. Does it matter if someone running for president is:

Mormon?
Atheist?
Muslim?
Scientologist?
Branch-Davidian?
Believes in UFOs?
Believes Elvis is alive?
