It'll be a woman. Religion trumps everything in American right now. There is no way that religious fanatics (well, actually they don't even have to be fanatics) will allow an atheist on board until several generations later. Gay is not even favorable yet b/c of the whole spew of family values... so that leaves us with a woman. Either way, the ultra conservative religious nuts would rather have none of the 3, but it'll start with a woman.
Definitely a woman. Let's hope the next three dozen are women. It's time we all tap this vital resource. Atheists know their mind, we've had them already. Gay dudes, we've had them, too. But if the last two keep their mouths shut, who's gonna know? Kiss a girl and say Amen, and that's it.
Most of the major leaders are Atheist but they attend church because it puts up a good front and is commonly accepted. Any religion they have is greed and the lust for power. Others may have been homosexual but if the media suspected they would keep it quiet, consider J. Edgar Hoover former head of the FBI and many who have had outside sexual interests that the media knew about but never told anyone publicly. While there has been no elected woman Presidents there were some that ran the country along with key aides when their husbands could not or would not do the job. I am sure sooner or later we will have an openly elected female President and they will do no better or worst than any of the others.
