among registered voters. With leaners it's Obama 48% McCain 43%. Poll was conducted over the period of September 23 – 28, 2008.
Interesting that one of the sponsors of this poll is Richard Mellon Scaife's Tribune Review.

Obama holds a sizable lead among younger residents, non-whites, college graduates, women, and residents of Philadelphia and Allegheny County. McCain has an advantage among men, Protestants, fundamentalist Christians, military veterans, and residents of Northwestern Pennsylvania (see Table A-1).
White working class voters narrowly favor McCain over Obama 44% to
42%, but his advantage among these voters has shrunk since August when he was
ahead 45% to 39%. McCain’s advantage among white men (51% to 30%) has
increased since August (48% to 36%) while Obama has increased his margin
among white women (49% to 36% now compared to 42% to 35% in August).
