Polls will be open in Nassau and Suffolk counties from 6 a.m. to 9 p.m.

With 95 delegates at stake, New York is the biggest prize up for grabs. Republicans in Pennsylvania, Connecticut, Rhode Island and Delaware also are going to the polls.

If any candidate wins more than 50 percent of the overall vote, he will get 34 at-large delegates. If not, those delegates will be distributed proportionally according to a candidate's statewide share.

The final three delegates will be state party officials.

Polls show Romney, the former Massachusetts governor, with a wide lead in New York. He's also won the most delegates to date and, with former Sen. Rick Santorum of Pennsylvania -- who was running second to Romney -- quitting two weeks ago, many national GOP leaders have endorsed him.
