Trump and Biden Win Primaries, but Voters Express Their Discontent

President Biden and former President Donald J. Trump won overwhelming victories in state primaries on Tuesday, while a small but significant protest vote in both parties continued to assert itself against each candidate.

Mr. Biden and Mr. Trump, who have already clinched their nominations, scored yawning leads in primaries in Connecticut, New York, Rhode Island and Wisconsin, with the races called shortly after polls closed in each state.

In Rhode Island, 14.9 percent of voters chose the “uncommitted” ballot option, or 3,750 votes, with turnout on the Democratic side roughly a quarter of that in 2020.

In New York’s Republican primary, Mr. Trump had above 80 percent of the vote, while Ms. Haley had 13
