With just under 7 weeks until PA’s April 26th primaries, the three Democratic candidates for U.S. Senate are beginning to make headway in their race to face incumbent Pat Toomey in November.

Though Sen. Toomey is still leading all three candidates, Democrats have eaten away at the gap over the last 6 months, according to the latest Harper Poll.

Former U.S. Congressman (and Toomey’s 2010 opponent) Joe Sestak does the best against Toomey – losing 47% to 41%. Toomey’s numbers have not changed since a September Harper Poll, while Sestak has picked up 4 points.

Katie McGinty is having trouble with name-recognition, with 40% unsure of how they feel about her. It’s not all bad news, however, as she has made “substantial” gains with her image in Philadelphia and the Southeast region and has narrowed the race by 6 points since September.

John Fetterman is also playing the name game with 57% of those polled unsure of who the Braddock Mayor is. That said, Fetterman still does well in his match-up with Toomey, losing 36% to 47%, with 16% of voters undecided.

Toomey is the only candidate for Senate with a positive favorability rating (49% – 40%), while 33% are still unsure of Joe Sestak – though he served two terms in Congress and has been campaigning for the seat since he lost it to Toomey in 2010.

Joe Sestak again comes out on top in a Harper Poll of likely Democratic voters, taking 33% to McGinty’s 17% – down from 28% in January – and Fetterman’s 15%. 32% of voters are still undecided, the poll shows.

Harper Polling surveyed 662 likely voters through landline interviews conducted using Interactive Voice Response (IVR). The poll took place between on March 1st and 2nd. The margin of error is +/- 3.75%.
