PPP's three day rolling national tracking poll finds Barack Obama pulling slightly ahead of Mitt Romney based on interviews conducted between Tuesday and Thursday. Obama's at 48% to 47% for Romney after leading by small margins with voters polled on each of the two nights following Tuesday's debate.
The numbers with Republicans and independents are unchanged after Monday's interviews were dropped off and replaced with Thursday's. But Obama's seen a small improvement with Democrats now, going from an 84/13 lead to an 86/12 one with his party base. Obama's deficit among white voters has also declined from 20 points at 58/38 to 18 points at 57/39. 20 points is something of a magic number in terms of what Romney needs to do with white voters in order to win the election, and if Obama can keep him below that he'll probably pull it out.
Obama is losing by small margins in every age group except for young voters- his 60/36 advantage with them provides his overall lead. The candidates' numbers along gender lines are completely opposite of each other- Obama leads 51/44 with women and Romney leads 51/44 with men.
Obama's approval remains steady at 46/50. Romney's favorability has dipped slightly back into negative territory at 47/48, the first time we've seen that in our national polling since his big victory in the first debate.
