2024 United States Senate election in Pennsylvania

2024 United States Senate election in Pennsylvania

The 2024 United States Senate election in Pennsylvania was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Pennsylvania. Incumbent Democratic Senator Bob Casey Jr. lost re-election to a fourth term, being defeated by Republican nominee Dave McCormick in what was considered a major upset. Most predictions gave Casey a slight advantage, and he led in most polls. Along with Sherrod Brown in Ohio and Jon Tester in Montana, Casey was one of three incumbent senators to lose re-election in 2024, all of whom were Democrats that were first elected in 2006. The primary election took place on April 23, 2024. The election was considered essential for Democrats' chances to retain their majority in 2024. The Associated Press and Fox News declared McCormick the winner on November 7, while Decision Desk HQ called the race for McCormick on November 14. CNN, NBC, ABC, and CBS all called the race for McCormick on November 21; Casey conceded the race later that day. A recount confirmed the result. This was Pennsylvania's closest US Senate election since the passage of the Seventeenth Amendment, as well as the closest Senate election of the 2024 cycle. McCormick was the only Republican challenger to win in a state flipped by Trump in the 2024 presidential election. The other three Republican Senate gains were in states Trump had won in all three of his runs. With Democrats winning the other Senate seat two years earlier, this was the first time since the 2012 Senate election in Indiana where the opposite party flipped a seat after losing one in the previous cycle. Notably, the margin of just 0.22% between the Republican and Democratic candidates is fewer than the votes received by either the Libertarian candidate, John Thomas (1.29% of the vote), the Green candidate, Leila Hazou (0.95% of the vote), or the Constitution candidate, Marty Selker (0.34% of the vote). This was Casey's first general election loss of his political career, and the second counting Casey's primary election loss in 2002. This election made Pennsylvania one of several states to have a younger senior senator (John Fetterman) and an older junior senator (McCormick). McCormick was sworn in on January 3, 2025.

  190. "I am an evangelical voter in Pennsylvania. Donald Trump could have had my vote had he not started to support most kinds of abortion and vowed to fund IVF with my tax dollars. I am casting my vote for @DustyDeevers as President and for @BradleyWPierce as Vice President. I know that both men fear the Lord and would establish justice if they were elected. I voted for some Republicans in state and local races, some third-party candidates like @JohnThomasPA who have vowed to protect the preborn, and wrote in qualified Christian men when there were no other options. None of this was necessary. I would have voted for Donald Trump or any other Republican candidate who vowed to protect the preborn and end mass child sacrifice in our nation. If the Republican Party wants evangelical votes, they cannot shirk evangelical policy priorities, and most importantly they cannot shirk their duty to obey and honor the Triune God and govern in their offices with justice and righteousness. I will not reward betrayal with my vote"
