As TPM has reported over the last few days, the prolonged debt debate is pulling down the approval ratings of national leaders, and PA is no exception. Obama beat Romney 47 - 40 in Quinnipiac's June poll, and Tim Malloy, assistant director of the Quinnipaic Polling Institute, urged caution. "Let's see how the public reacts to the news and whether today's results are a baseline for measuring future results, or whether they show the president is in big trouble in Pennsylvania, a key swing state," Malloy wrote.
Still, Romney now leads Obama by a slim .4% margin in the TPM Poll Average of the matchup in Pennsylvania.
The new Quinnipiac poll utilized telephone interviews with 1,358 registered voters and has a margin of error of plus or minus 2.7 percent for the general election matchup. For the Republican sample, there were 532 interviews and a 4.3 margin of error.
