McCain or Obama on vaccine damage?

John McCain did catch my attention when in the primaries he said something about looking into vaccines as a cause of autism.

But then he went all "Walnuts" as Wonkette would say, and I don't know half of what he is saying anymore.

In this Age of Autism piece, it appears McCain IS more responsive to things like parental choice, etc., http://www.ageofautism.com/2008/10/mccain-or-oba-1.html#more

But personally, I've been in the tank for Obama from day 1, and when I look at his picture, I feel happy and calm...when I look at McCain, I feel blech. Well, there is an autistic young man who agrees with me on this, so McCain's admittedly more bold stance on vaccines isn't enough to make me switch:
