We've definitely already had a few. If you are talking about an "open" atheist, then it is probably a state in New England. Maybe Maine. I think Alaska is kookier than most people perceive it to be.
Kooky maybe, but not in a religious way. It's one of the least religious States.
I'm aware, but the least religious state in America is still
pretty religious, and the politically active conservatives that elect most of the statewide officials in that state certainly are. Everyone Alaska has put on a national stage has been a little nutty. It's got a unique culture to it, for sure. That's why I don't think Alaska is going to give us our first open atheist. It's just my opinion.
