To make the question simpler then:A republican can respond to your question by asking if you would vote for a scientific minded democrat with ridiculous ideas as opposed to a creationist republican who had fairly sound ideas in all other areas?
Who would you, as a republican, rather vote for: Obama or Huckabee?
If evolution is a minor question for most americans, that's quite scaring. If people are not capable of spotting an (or actually, several) obvious nutcase(s), you can be sure a nut ends up in the top. (Well, we've already seen this happen. After his first four years it was pretty obvious GWB didn't have all his sandwiches in the picnic basket, and he still got reelected.)Realistically speaking, evolution is not a big deal for most people. If a republican candidate promises a middle class taxcut while a democrat promises raisig taxes to balance the budget, something like evolution goes to the back of the line in terms of importance. Unless you have parkinsons disease, then things like stem cells, evolution, and creation become more important.
