Trump Wins Pennsylvania Primary, but Remains Haunted by Haley

Donald J. Trump and President Biden scored overwhelming primary victories in the battleground state of Pennsylvania on Tuesday, facing opponents who had long since dropped out of the race.

Mr. Trump appeared to take 83 percent of the vote against Nikki Haley, his former rival in the Republican primaries.

Ms. Haley, the former South Carolina governor, did not endorse Mr. Trump in exiting the race, and the Pennsylvania vote reflected his continuing difficulties in wooing her supporters and in fully winning over the Republican electorate. In G.O.P. primaries earlier this month in Wisconsin, Rhode Island, Connecticut and New York, Ms. Haley won small but significant protest votes — capturing at least 10 percent of the vote in each of the four states.

On the Democratic side, Mr. Biden, who grew up in Scranton, Pa., took nearly 95 percent of the vote. Representative Dean Phillips, who was on the ballot but dropped out of the race last month, got about 5 percent of the
