Huntingdon Valley, PA, October 7, 2010—In a poll conducted by Neil Newhouse, Public Opinion Strategies, it was revealed that the PA 13th Congressional Seat held by incumbent Democrat Rep. Allyson Schwartz is not “Safe” as many have predicted. In a summary memo, Neil Newhouse said, “Forget the Democrat registration edge here, voters in this district are leaning toward the GOP candidate in the November election by a 44%-42% margin, with even 27% of Democrats supporting a ‘checks-and-balances’ Republican. Voters here are clearly looking for a change.”
