In the 1,325-voter sample, Obama leads Sen. John McCain 52 percent to 36 percent. The lead remains 15 points among likely voters.

Obama’s support includes a 17-point advantage among independents and a sizable lead in every age and income group. The candidates are tied among white voters, while Obama leads 90 to 1 among blacks. The only voter categories in which Obama trails McCain are subcategories of the white vote: white evangelicals, white men, whites over the age of 50 and whites with no college education.

Among voters in the battleground states of Colorado, Florida, Indiana, Iowa, Michigan, Minnesota, Missouri, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin, Obama holds a comfortable 53 to 35 lead.

Looks like Nov. 4 could be an early night — but as they say, it ain’t over till it’s over.
