Now that John McCain is the Republican nominee for president, a lot of people are paying far more attention to what he says on the campaign trail.
And although he doesn't talk much about education, he may have stepped on a landmine when he waded into the controversial area of what causes autism. Specifically, he said there's "strong evidence" that a preservative in vaccines is causing autism, according to this New York Times story.
What strong evidence?
I asked a colleague who knows far more about special education issues. And as Christina Samuels points out in her blog post, the Centers for Disease Control and Prevention say there is no link.
Of course, there are a lot of parents out there who don't believe that. (Update: Plus, I found this story in yesterday's USA Today.) The question is, has McCain taken the time to look into all the evidence out there?
