The 2024 United States Senate election in Pennsylvania will be held on November 5, 2024, to elect a member of the United States Senate to represent the state of Pennsylvania. Primary elections will take place on April 23, 2024. Incumbent three-term Democratic Senator Bob Casey Jr. announced his intention to run for a fourth term on April 10, 2023.
Background
Pennsylvania is considered to be a purple state at the federal level, especially since in the 2020 presidential election, Joe Biden carried Pennsylvania by about 1.2 percentage points. Democrats currently control both U.S. Senate seats, the Governorship, a majority of its U.S. House congressional delegation, and the Pennsylvania House of Representatives. The last time Republicans won a U.S. Senate seat was in 2016.
Senator Bob Casey Jr. was first elected in 2006, defeating then-incumbent senator Rick Santorum by about 17 percentage points. He was re-elected in 2012 by 9 percentage points and in 2018 by 13 percentage points.
The race is considered to be favoring Casey, but analysts still consider this race to be amongst the most competitive Senate races in 2024.
