Today PPP is releasing the first results from the daily tracking poll it will be running for the rest of the election, sponsored by Americans United for Change. It will be based on a three day rolling average, with 400 interviews conducted each day.

Based on interviews completed between Monday and Wednesday Barack Obama and Mitt Romney are all tied up at 48%. This represents some improvement for Obama compared to PPP's last national survey, conducted last weekend for Daily Kos and SEIU, which found Romney up 50/46.

Obama is up 51/45 with women, 62/34 with Hispanics, 87/8 with African Americans, and 57/38 with young voters. Romney is ahead 50/45 with men, 46/41 with independents, 58/38 with whites, and 53/43 with seniors.

Voters narrowly disapprove of Obama's job performance, with 46% of voters giving him good marks to 50% unhappy with how he's doing. That's actually up a little bit from a 44/53 spread over the weekend though. Americans are split right down the middle in their assessments of Romney- 47% see him favorably and 47% unfavorably. That's down from a 49/45 spread on last weekend's survey.

With less than three weeks to go until election day, this race couldn't be much more of a toss up nationally. We'll keep you apprised of the daily movement.
