In the current version of Rolling Stone, Matt Taibbi dissects Michelle Bachman. The biggest question is whether she is a nutcase or a knowing fraud, or both:

Bachmann's story, to hear her tell it, is about a suburban homemaker who is chosen by God to become a politician who will restore faith and family values to public life and do battle with secular humanism. But by the time you've finished reviewing her record of lies and embellishments and contradictions, you'll have no idea if she actually believes in her own divine inspiration, or whether it's a big con job. Or maybe both are true — in which case this hard-charging challenger for the GOP nomination is a rare breed of political psychopath, equal parts crazed Divine Wind kamikaze-for-Jesus and calculating, six-faced Machiavellian prevaricator. Whatever she is, she's no joke.
