lol Christianity has denominations: protestant, and catholic, etc. baptist is protestant. protestants are from martin luther, he challenged the roman catholic church because at the time they were very corrupt. so you are telling me, the essence of challenging corruption makes protestantism crazy? what? christian denominations are mainly the same, with some differences.
btw, its not their religion that makes them bad presidents, the problem is much deeper than just that. (the president isn't the only one with power, it's the people that he selects, it's the people that he makes decisions with (the think tank institution is very influential on the president's decisions), it's the people that tell him what to do, what to say, when he becomes president, and obviously the potential president will not be picking with top priority of which denomination.)
