The answer is pretty clear. Obama is running for the DEMOCRATIC nomination. Williams ran and won as an independent. Obabma certainly didn't want to offend the very democrats he is trying to woo by acknowledging a democratic stray sheep like Williams. If Obama gets the Democratic nomination he is more likely to acknowledge Williams and other independents that could help him win the general election.
