Barack Obama and Mitt Romney are dead even at 48% headed into tomorrow's debate, based on an average of PPP's national tracking between Friday and Sunday. Barack Obama had a small lead in Friday interviews, Mitt Romney had a slight advantage on Saturday, and the candidates were dead even on Sunday.
Our tracking isn't providing any real surprises along demographics lines. Obama is up 50/46 with women, 61/33 with Hispanics, 85/9 with African Americans, and 50/39 with young voters. Romney is up 51/44 with men, 57/39 with whites, and 51/47 with seniors. One key for Romney is that he's up 51/41 with independents, which helps him make up for the party identification advantage Democrats have nationally.
Obama's approval rating is 45% with 50% of voters disapproving of him, making it important that he make a compelling case for voters tomorrow night about why his first term has been a success. Romney's favorability rating is back on positive ground at 49/45, while Obama's is dead even at 48/48.
Here's the state of the race headed into the final debate: it's tied nationally, and the candidates are within 2 points of each other on the most recent PPP surveys in the critical swing states of Florida, Iowa, New Hampshire, North Carolina, Ohio, Virginia, and Wisconsin. It could not be a whole lot closer.
