Race looks to be a key factor, with African-Americans, who made up just over half the poll sample, favoring Obama over Clinton 65% to 16%. Among whites, Clinton and John Edwards are nearly tied with 33% and 32%, while Obama trails at 18%. "Obama is doing very well among African-Americans, but getting a decent share of the white vote in a three-way race," commented a pollster. Most of the polling was done before Monday night's ill-tempered debate, when Edwards urged Clinton and Obama to stop squabbling. Preliminary polling done after the debate showed Edwards had made some slight gains. Read These Next One wrong step costs teen at Yellowstone. Murdered couple died "protecting their little girls."
