Saw this editorial cartoon. Kind of interesting:
I read a statistic that said that the African American community voted 69-31 in favor-against prop 8 yesterday, though now, of course, I can't find my source, so take that with a heaping pile of salt. There was a lot of concern leading up to the election that increased minority turnout in favor of Obama would seriously harm the prop 8 campaign, though, and it looks like they were correct. While that's certainly not the only reason it passed, it seems to have made a difference.
