The survey, which was conducted April 15-16, 2008 and came out of the field midway through Wednesday's contentious debate between the two candidates in Philadelphia, shows Clinton at 45% and Obama at 44%, with 12% either wanting someone else or left undecided.
The telephone survey, conducted using live operators working out of Zogby's on-site call center in Upstate New York, included 601 likely Democratic primary voters in Pennsylvania. It carries a margin of error of +/- 4.1 percentage points.
yesterday's public policy poll also puts the race at about even.
