Barack Obama 53
John McCain 45
Barack Obama's lead in the Keystone State has decreased from the consensus several weeks ago that he had a double digit advantage but he nevertheless is in great shape to take the state with an eight point lead and almost nobody undecided.
Obama has a commanding 56-38 lead with independent voters in the state. As he is in many swing states, Obama is actually carrying more Republican voters (16%) than John McCain is Democratic voters (15%), perhaps surprising in a state where Hillary Clinton won the primary in a walk.
Obama is trailing McCain only 50-48 among white voters. In a state with a black population over 10% that level of competitiveness is more than enough to give him a strong overall lead when you factor in his 90% + support from African American voters.
Obama is winning in every age demographic except senior citizens and a large amount of his lead is coming from a remarkable 68-30 performance with voters under 30.
In Pennsylvania down ballot races Republican Tom Corbett leads 52-35 for Attorney General, holding Democratic challenger John Morganelli to 59% even among voters within his own party. For Treasurer Democrat Rob McCord leads 46-38 and for Auditor General Democrat Jack Wagner leads 49-35.
