Fondren, granted that there are have been evangelicals who have run for office on a platform dominated by their religious point of view (Robertson, Huckabee, and remember that Jesse Jackson is a minister). However, the nice thing about living here is that anyone who meets the qualifications set out in the Constitution has every right to run for POTUS or any other office. And one needs only to look at how these candidates fare in elections (Huckabee in the tank presently, Robertson and Jackson never having been viable candidates in their time) to see that the threat of the US becoming a theocracy is negligible at best. As for your examples, I can't recall any credible politician advocating the return of prayer in public schools. As for a constitutional amendment to ban gay marriage, those who have advocated it have done so not for religious reasons, but rather for the sake of preserving their idea of what a family should be (a vehicle in which children are given the best possible environment for growing into well adjusted adults). Definitely not trying to start a gay marriage duscussion here; just making the case that your example is not a great one in the context you used it. What were we talking about anyway? Switching religions, right?
