Pennsylvania midterm elections: House and Senate seats, candidates, issues and more

Pennsylvania's Senate and gubernatorial races are among the most critical races in the midterm election on Nov. 8.

In total, the midterm elections will put 35 Senate seats, 435 House seats and 36 gubernatorial seats up for grabs. Republicans only need to win a net of five seats in order to regain the House and must win a majority of the swing state Senate races, such as Pennsylvania, Nevada and Arizona, in order to take that chamber of Congress. Pennsylvania is one of the states Democrats must flip in order to help ensure they keep their existing majority for the 118th Congress.

In prior presidential elections, Pennsylvania has become a swing state in the Rustbelt, flipping for the first time in decades to Donald Trump in 2016 and then back to the Democrats in 2020 for President Joe Biden.
