Sen. Barack Obama's historic victory in the Democratic primaries has sparked an increase in racist and white supremacist activity, mainly on the Internet, according to leaders of hate groups and the organizations that track them. "I haven't seen this much anger in a long, long time," said Billy Roper, a 36-year-old who runs a group called White Revolution in Russellville, Ark. "Nothing has awakened normally complacent white Americans more than the prospect of America having an overtly nonwhite president."
