Just realized that the link I provided is the same McCain interview referenced by Mark (and Murrell) above. More discouraging stuff to be found in there, including his admission that he'd leave it up to school boards whether or not to teach evolution. (I'm reminded of the line that the theocons are against evolution because it hasn't happened to them yet.)
Q: How do you feel about teaching evolution in schools?
Mr. McCain: I think, first of all, it’s up to the school boards. That’s why we have local control over education. So my personal view is that children should be exposed to as much as they possibly can so that they can make their decisions and be the best informed. But I really believe that school boards are elected in order to make a lot of those decisions, and I respect their decisions unless they are unconstitutional in some way or, you know.
Q: If you were on a school board, how would you vote?
Mr. McCain: I don’t know, Adam. I’d have to see the proposal, I’d have to see where it lies in the curriculum, I’d have to – I can’t. I’m not running for school board.
