Yeah, he was conservative, supported George W. Bush and all. I think Vanities has dated a bit, though I don’t recall any of the race/class stuff in it being really bad or anything, maybe just cliche. He’s taking pot-shots at the white middle/upper-class really.
I read A Man in Full which was OK (some great bits but it’s way too long), though I heard his subsequent novels weren’t too good so I never read them.
