Joe Sestak’s lead over Katie McGinty for the Democratic Senate nomination has dwindled to just 6 points, according to the latest Franklin & Marshall poll.

The former Congressman held a 17-point lead over McGinty a month ago, but it now seems to be anyone’s race.

Sestak picked up 33% in the poll, with McGinty trailing close behind on 27%. Braddock Mayor John Fetterman, with 8% in the poll, still has a chance to win if he can swing the 29% of voters who are still undecided.

Even those who believe they have made up their minds aren’t quite so sure, the poll shows. 30% of likely Sestak supporters and 36% of likely McGinty supporters said they are still making up their minds.

Sestak triumphs over his challengers with voters at all income levels and picks up some of his strongest support from those over the age of 55 (40%). Likewise, Sestak found strong support from retired workers (39%), though McGinty leads Sestak by a slim margin with full-time employees (26-24%).

Fetterman edges out his competitors with likely voters under 35, while McGinty leads with voters 35 to 54, the poll shows.

While Gov. Tom Wolf’s former Chief of Staff leads in Philadelphia, Allegheny and Southwest PA, Sestak has won over the Northeast, Central and Southeast regions.

McGinty and Sestak split the Northwest with 30% each.

Fetterman’s strongest support comes from the Allegheny region, where he ties Sestak for second with 23%.

Some good news for Sestak, though, is that this survey shows him retaining his lead as yesterday’s Monmouth poll had the race tied.

This poll was conducted by the Center for Opinion Research at Franklin & Marshall College. They surveyed 510 registered Pennsylvania Democratic voters from April 11th to April 18th. The margin of error is +/- 4.2%.
