Former Rep. Marjorie Margolies’ new poll shows her with a strong lead in the 13th District primary, boasting a 28-point advantage over her closest Democratic opponent.

The Pennsylvanian is attempting a comeback bid two decades after losing re-election to the House.

The poll, released Wednesday, shows her garnering 48 percent of the vote in a four-way primary, followed by state Rep. Brendan Boyle, who picked up just 15 percent.

The other two primary candidates — state Sen. Daylin Leach and University of Pennsylvania Medical School professor and physician Valerie Arkoosh — would draw 7 percent and 2 percent of the vote, respectively.

Margolies also has the highest name recognition of the group, with 81 percent of voters familiar with her.

Margolies represented the 13th District for one term in 1993. She lost re-election after casting an unpopular vote for President Bill Clinton’s deficit reduction plan. She attempted to run again for Senate in 2000, but withdrew from the race due to family and financial troubles stemming from her ex-husband’s legal issues.

All four candidates are running to replace Rep. Allyson Y. Schwartz, D-Pa., who is running for governor.

Although Margolies had a lead in the poll, she was the weakest of the pack in the fundraising race in the second quarter.

The Global Strategy Group surveyed 422 registered voters via live interview phone calls between Aug. 13 and Aug. 15. The poll had 4.8-percent margin of error.

Pennsylvania’s 13th District is rated a Safe Democratic contest by Rothenberg Political Report/Roll Call.
