Connecticut, New York, Rhode Island and Wisconsin get their say in presidential primaries

Voters in four states will weigh in Tuesday on their parties' presidential nominees, a largely symbolic vote now that both President Joe Biden and former President Donald Trump have locked up the Democratic and Republican nominations.

In particular, the tallies in Wisconsin, a pivotal November battleground, will give hints about the share of Republicans who still aren't on board with Trump and how many Democrats are disillusioned with Biden. Trump was scheduled to campaign Tuesday in Wisconsin and Michigan, two Midwest battlegrounds.

All four states have multiple candidates on the ballot, and three of them also have an option to vote for “uncommitted” or “uninstructed delegate.” Biden has faced opposition from activists encouraging Democrats to vote against Biden to send a message of disapproval for his handling of the war between Israel and Hamas.
