Every Republican nominee is a fundamentalist Christian (or a conservative Mormon which isn't much different). Rick Perry, who is likely to have a shot at winning the Republican nomination, started his campaign with a fundamentalist Christian prayer rally.
Even Democrats need to be Christian to have a real chance to win a national office.
It doesn't seem like Libya is much different than the US in this respect. Libya isn't my country. I am much more worried about the impact of Christian Fundamentalists here.
