That's the biggest lead for Obama. Rasmussen and Gallup have him up 3 points.
Obama led McCain among independents, 47 percent to 35 percent, and led among some groups of voters who have backed Clinton during their Democratic primary battle, including Catholics, Jews, union households and voters making less than $35,000 a year.
McCain led among whites, NASCAR fans, and elderly voters. McCain led with voters who believed the United States was on the right track, and Obama led with the much higher percentage of voters who believed it was on the wrong track.
