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 155,000 votes across the state. That exceeds the margin of 81,660 votes by which Mr. Biden won the state in the 2020 election.

In the past two weeks, Mr. Biden has had the campaign trail largely to himself while Mr. Trump sits in a Manhattan courtroom for a felony criminal trial related to a 2016 campaign sex scandal cover-up. Wednesday, however, is a day off from the proceedings.

Mr. Biden plans to deliver remarks today at a conference for North America’s Building Trades Unions, an umbrella labor group. Vice President Kamala Harris will be in New York today to record an interview with Drew Barrymore for her television talk show. Tomorrow, Mr. Biden will head to Syracuse, N.Y., for a White House event, while Mr. Trump will head back to court.

In Pennsylvania on Tuesday, a long-awaited Senate matchup was officially set, 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.
