In the former case, yes that's racist but there were probably fewer of them this election than the last. Also, there were probably fewer of them than voted against him because he's black.
WRT the latter, you don't have to reveal who you voted for so I doubt many did so out of fear (except maybe at those polling stations in Philly manned by the Black Panthers.) Peer pressure is a problem in elections, but it works in both directions.
