A recent Suffolk University/USA TODAY Network poll shows John Fetterman with a nine-point lead over Mehmet Oz in the Pennsylvania Senate race.
Fetterman had the support of 46 percent of likely voters in the state of Pennsylvania, while Oz had 37 percent.
In the poll, voters from each political party lined up behind Fetterman and Oz, with Fetterman getting the majority of the Democrats' support.
Fetterman is doing a better job of keeping his base, as only six percent of Democrats cross over to back Oz, while ten percent of Republicans say they will vote for Fetterman.
Fetterman won 44 percent of the vote, compared to Oz's 24 percent with this group. 26% of independents said they were undecided.
Fetterman has a 45 percent favorable rating with Pennsylvania voters and 27 percent unfavorable. Oz has an unfavorable rating of 50 percent and a favorable one of 28 percent.
Oz, a cardiothoracic surgeon best known for his nationally-syndicated talk show, won a multicandidate GOP primary last month by a small margin. While former President Donald Trump supported Oz, his top rival was very close to capturing the nomination.
Over the past year, President Joe Biden's standing in the state has deteriorated, with 53 percent of the population viewing him unfavorably.
54 percent of Pennsylvania's population disapprove of the president's performance, while 39 percent approve.
Fifty percent of respondents said they wanted their vote to change the direction in which Biden is leading the country.
Fetterman, who has developed a personal brand as a nontraditional politician over the years and frequently campaigns in rural and exurban areas that have turned sharply against Democrats over the past decade, is performing better than Biden.
While Republicans are poised to make major gains in Congress this year, national Democrats are optimistic about their chances in Pennsylvania, a state that Biden narrowly won in the 2020 presidential election.
The Republican senator decided to retire after two terms in office.
13 percent of respondents were undecided in the open Pennsylvania governor's race, where the Democratic Attorney General holds a 4-point lead over his Republican opponent.
Eighty-three percent of Republicans say they'll vote for Mastriano, while 81 percent of Democrats say they're going to vote for Shapiro.
Mastriano defeated a group of GOP candidates in a primary last month.
In recent weeks, Mastriano has begun to rally the conservative base around his general election candidacy, despite the fact that he has been painted as outside the political mainstream on major issues.
The survey had a margin of error of plus or minus 4.5 percentage points.
