Barack Obama 45
Hillary Clinton 42
It seems more clear with each passing day that Hillary Clinton's efforts to hurt Barack Obama for his 'bitter' remarks are not working. Earlier this week PPP showed Obama maintaining a 20 point lead in North Carolina, and now for the third week in a row we show the race in Pennsylvania as a statistical tie.
Obama's gain since PPP's poll last week is not attributable to any major shifts of support from any particular demographic. He simply cut Clinton's lead with whites and women, and increases his advantage with men and black voters.
High turnout in the metro Philadelphia area seems likely to be the key to Obama's success or failure. Right now he leads 53-33 in that region, with Clinton showing a strong advantage in most of the rest of the state.
This race could go either way depending on how the campaign unfolds over the last week. If Obama does win, it may be that his superior ground game ends up making the difference to put him over the top in the closing days.
