I'd say the chances of the Obama campaign taking advice from Steve Sailer are low, but you never know what might happen to a meme when it's out there.
Sailer's dead right. The person Obama most needs to distance himself from is his younger self. What Obama needs is a "I used to be a radical... but then I had kids" speech. If he does that, he wins the election in November. If he doesn't, it's Presiden McCain.
Actually, I imagine such a speech would be quite good.
