One of the principle attacks against Sarah Palin as John McCain's choice for VP is her support of "alternative" theories about biological diversity. According to an AP article out today:
As a candidate for governor, Sarah Palin called for teaching creationism alongside evolution in public schools. But after Alaska voters elected her, Palin, now Republican John McCain's presidential running mate, kept her campaign pledge to not push the idea in the schools. As for her personal views on evolution, Palin has said, "I believe we have a creator." But she has not made clear whether her belief also allowed her to accept the theory of evolution as fact. "I'm not going to pretend I know how all this came to be," she has been quoted as saying.
If the left blows this up, you can be sure the news media will pick it up but I am guessing it is a non-starter.
