During the Democratic primaries, Hillary Clinton usually left Barack Obama in the dust when it came to voters with less formal education and he also ran behind John McCain among them. But now Obama has apparently erased McCain's advantage with this demographic, according to a Gallup tracking data collected during June. The two candidates split that vote at 43 percent each, a change from March when McCain led by 7 points. So, Obama may be gaining back this key Democratic constituency.

McCain had led Obama in March and April by 11 and 12 points respectively among men with a high school education or less, and now that lead is down to 4 points. McCain had a smaller lead among women in this group, in the 3 to 4 point range, but now Obama leads by 4 points. Obama has made progress but still lags badly among whites when these voters are sorted by race. McCain had a 23 point lead in March and still is ahead by 17 points. Among non-whites, Obama has had giant leads all along, and bests McCain by 56 points.
