The Gallup poll released Wednesday showed McCain leading Obama by 13 percentage points among non-Hispanic white men -- a drop of 8 percentage points from a poll taken during the month of August.

Among white women, Obama's lead over McCain in both polls remained the same at 4 percentage points, Gallup reported, noting Obama in polls shows a huge lead among both black men and black women, and leads among Hispanics, regardless of gender.

The survey taken Saturday through Monday interviewed 2,772 registered voters by telephone and had a margin of error of 2 percentage points.
