Three Takeaways From the Pennsylvania Primaries

With the 2024 primary season entering the homestretch — and the presidential matchup already set — hundreds of thousands of Pennsylvanians cast their ballots on Tuesday in Senate and House contests as well as for president and local races.

President Biden and former President Donald J. Trump, who had been heading toward a 2020 rematch for months before securing their parties’ nominations in March, scored overwhelming victories in their primaries, facing opponents who had long since dropped out of the race. But Nikki Haley, Mr. Trump’s former rival in the Republican primaries, still took more than 100,000 votes across the state.

A long-awaited Senate matchup was officially set, as well, as David McCormick and Senator Bob Casey won their uncontested primaries.

And Representative Summer Lee, a progressive first-term Democrat, fended off a moderate challenger who had opposed her criticism of Israel’s war in Gaza. While Mr. Biden has faced protest votes in a number of states, Ms. Lee’s race was one of the first down-ballot tests of where Democrats stand on the war.

Here are three takeaways.

A progressive Democrat fended off a challenge that focused on her criticism of Israel’s military campaign.

Ms. Lee, a first-term progressive Democrat who represents a Pittsburgh-area district, was an early critic of Israel’s war in Gaza, where about 34,000 people have died since the war began six months ago. Ms. Lee’s stances against Israel’s military campaign drew a primary challenge from Bhavini Patel, a moderate Democrat who opposed Ms. Lee’s approach on the war.

But Ms. Lee emerged victorious, suggesting that public sentiment on the war, particularly among Democrats, has shifted significantly against Israel in the six months since the war began.
