Democratic incumbents running for reelection in Pennsylvania hold double-digit leads over their Republican opponents, according to a Franklin & Marshall College poll released Thursday.

Casey, a two-term senator, has a 41 percent approval rating, according to the poll. Barletta, meanwhile, is hurt by low name-recognition, with 53 percent of voters not knowing enough about him to give an opinion.

Pollsters also found that Gov. Tom Wolf (D-Pa.) holds a 17-point lead over state Sen. Scott Wagner (R), 52 to 35 percent. Twelve percent of voters remain undecided in that race.

Wolf, who is running for his second term, has a 46 percent approval rating in the new survey. He too is aided by his opponent’s low name recognition, with 42 percent of registered voters not knowing enough about Wagner to give an opinion.

Both Democrats are also buoyed by President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE’s low approval rating in the state, which stands at about 38 percent in the poll. Trump won Pennsylvania by less than 1 percent in 2016 and has endorsed both Barletta and Wagner.

Regardless of party, Trump is a potent motivator for voters. About 67 percent of those who intend to vote for a Democrat say they will do so as a vote against the president and Republicans in Congress. About 74 percent of those who intend to vote for a Republican say they do so in support of the president and Republicans in Congress.

This is the second poll in as many weeks to show Casey and Wolf with double-digit leads over their opponents. An NBC News–Marist poll released last Thursday showed similar margins in each race.

Franklin & Marshall College interviewed 511 registered voters in Pennsylvania from Aug. 20 to 26. The poll has a margin of error of 6.1 percentage points.
