Qualifications for president and evolution

People have a right to believe whatever nonsense they wish, but the idea of electing representatives means the electorate must decide who is qualified to lead them (since we no longer believe in divine right in the modern world). But when candidates today say they "don't believe in evolution" they should be disqualified by the electorate. The reason is not due to them violating church-state separation or not having attained a sufficient level of knowledge to function in the real world (since they have being that all main candidates are wealthy and successful in their own rights), it is due to there lack of reason and disjoint views from reality coupled with being the Commander-in-Chief.

Evolution has more evidence than any political or economic situation will ever have and if they cannot accept the facts with such overwhelming evidence it is worrying what will happen in situations with much less evidence. We have seen first hand what happens when a belief is touted as fact (WMD's in Iraq for instance) and a president who cannot either admit he does not know enough about biology to comment or make an informed decision but rather takes the word of religious officials is a liability for the country.
