Pennsylvania political junkies didn't expect a boring year in 2024, but nobody quite predicted the 2024 Pennsylvania Senate election would turn into a nail-biter that stretched weeks past the actual voting day. If you live in the Keystone State, you probably couldn't turn on a TV without seeing Dave McCormick or Bob Casey Jr. arguing about "greedflation" or Connecticut mansions. It was loud. It was expensive. And honestly, it was a bit exhausting.
For a long time, Bob Casey seemed like he was on a safe path to a fourth term. He’s the son of a beloved former governor and has been a staple of Pennsylvania politics since the 90s. But things shifted. Dave McCormick, the former Bridgewater Associates CEO who lost a heartbreaker of a primary to Dr. Oz in 2022, came back with a much more disciplined machine. He wasn't just running against Casey; he was running against the entire economic "vibe" of the last four years.
The Night Everything Changed
On November 5, the numbers started trickling in, and the mood in the Casey camp shifted from cautious optimism to genuine concern. Pennsylvania is a massive state with wildly different demographics, from the deep blue pockets of Philadelphia and Pittsburgh to the "T" shaped red middle.

McCormick didn't just win; he carved out a path that relied on flipping the script in places that used to be Democratic strongholds. He leaned heavily into the idea that Casey was a "do-nothing" career politician. It worked. By the time the Associated Press called the race on November 7, McCormick had a lead of about 30,000 votes.
Why the Recount Mattered
The margin was razor-thin. We're talking 48.8% for McCormick and 48.6% for Casey. In Pennsylvania, if the gap is under 0.5%, a statewide recount is automatically triggered. This wasn't just a formality. It cost taxpayers an estimated $1 million and kept the entire country's eyes on county election boards for the better part of November.
- The Legal Fight: There were huge arguments over "undated" mail-in ballots. Some counties wanted to count them; the Republican National Committee sued to stop it.
- The Concession: Eventually, the math just wasn't there for Casey. On November 21, he finally conceded, acknowledging that the roughly 16,000 to 17,000 vote gap wasn't going to vanish.
The Issues That Actually Moved the Needle
You’ve probably heard a million times that it was all about the economy. And yeah, it was. But it was also about how each candidate framed that economy. Casey talked about "shrinkflation"—the idea that companies are giving you fewer cereal flakes for the same price. He tried to play the role of the populist fighter for the little guy.
McCormick countered by pointing at the grocery bill. He basically told voters, "Look at your life four years ago versus now." He linked Casey to every unpopular policy of the Biden administration, and in a state where the presidential race was also leaning right, that strategy had a lot of gravity.
McCormick also had to dodge the "carpetbagger" label. Casey's team spent millions on ads showing McCormick's life in Connecticut. They wanted voters to think he was just some rich guy trying to buy a seat. McCormick fought back by highlighting his roots in Bloomsburg and his time wrestling in high school. He painted himself as a successful PA son who went out, made a fortune, and came back to save the state.
The Abortion Shift
One of the more interesting subplots was Casey's evolution on abortion. He used to call himself a "pro-life Democrat." After Roe v. Wade was overturned, he shifted his stance to support federal protections for abortion access. This was a gamble. He needed to energize the suburban voters in the "collar counties" around Philly, but it might have cost him some of those older, more conservative Catholic voters in the northeast who had supported him for decades.
A Massive Spending Spree
If you felt like the ads were everywhere, you weren't imagining it. This was the second-most expensive Senate race in the entire country. We are talking over $300 million spent between the campaigns and outside groups.

The Keystone Renewal PAC, a pro-McCormick group, dumped about $54 million into the race alone. On the other side, Casey out-raised McCormick in individual donations, pulling in about $52.9 million compared to McCormick's $27.7 million. But McCormick's personal wealth and his deep-pocketed allies in the finance world leveled the playing field.
What This Means for Pennsylvania’s Future
With McCormick sworn in on January 3, 2025, Pennsylvania's representation in the Senate looks very different. You have John Fetterman, who is... well, he's John Fetterman. And now you have Dave McCormick. It’s a split delegation that reflects just how purple the state remains.
McCormick's win was a signal that the "Blue Wall" in Pennsylvania has some serious cracks. He was the only Republican challenger in the country to flip a Senate seat in a state where the presidential winner also flipped. That’s a big deal. It shows that his message resonated even with some people who might have been skeptical of the top of the ticket.
Actionable Insights for the Next Cycle
If you're following Pennsylvania politics, here are a few things to keep an eye on as we move toward the next elections:

- Watch the Margins: The 0.22% gap in this race shows that third-party candidates (like John Thomas or Leila Hazou) actually had enough votes to play spoiler. In a state this close, every small faction matters.
- Follow the Money: The influence of massive PAC spending isn't going away. If anything, the 2024 race proved that "outside" money can effectively counter an incumbent's name recognition.
- Pay Attention to the Courts: The legal battles over which ballots count (undated, misdated, etc.) are far from over. Expect the legislature to take another crack at "clarifying" the state's election laws before 2026.
- Voter Realignment: Keep an eye on the "Luzerne County" types—formerly blue-collar Democratic areas that are now firmly in the Republican column. If Democrats can't win back some of those voters, the state's math gets much harder.
The 2024 Pennsylvania Senate election wasn't just another race; it was a shift in the state's political DNA. Whether you're happy with the result or not, it’s clear that the old rules of Pennsylvania politics—where a famous name like Casey was enough to carry the day—don't necessarily apply anymore. It’s a whole new game now.
