If President Obama got a “bounce” from the killing of Osama bin Laden among Pennsylvania voters, the benefit has since melted away.
A poll released Thursday by Susquehanna Polling & Research finds that the president is “upside down” in the state, with 48 percent of voters disapproving of his performance and 41 percent approving. The negative rating is 3 percentage points higher than the firm’s same poll in March.
 The big problem for Obama: defections among Democrats. Voters in Obama’s own party rate his performance at 61 percent positive to 30 percent negative – compared to March’s 69-21 percent ratio.
 The automoated telephone poll of 1,406 registered voters statewide was conducted from May 30 through June 2, a time period that coincided with a flood of negative reports on the economy and turmoil in the stock markets. Not surprisingly, 50 percent of respondents said the economy in Pennsylvania had worsened over the past 12 months, while 16 percent said it had improved. Thirty-five percent rated the economy about the same as a year ago.
On the re-elect question, 43 percent of Pennsylvania voters say that Obama deserves a second term, while 50 percent say that it is “time to give someone else a chance.”
Wrote Jim Lee, president of SP&R: “The fact that 1 in 2 voters are looking for someone else suggests that President Obama has little room to grow and that Pennsylvania will again be a toss-up state in next year’s presidential election, particularly if the slow economic recovery continues to haunt the president.”
