(WBNG Binghamton) Voters in Pennsylvania, Connecticut, Delaware, New York and Rhode Island will head to the polls to cast their votes in Tuesday's primary.
New York will have 95 delegates up for grabs, but the winner of the primary won't necessarily take all.
Unlike previous years, delegates will be distributed by New York's 29 congressional districts.
Pennsylvania offers 72 delegates divided amongst its congressional districts.
Although Rick Santorum, Mitt Romney's most supported challenger has dropped out, Republicans say voting in their primary is important.
"Primary votes tend to have low turnout in general. People don't view them as important as the big November election, and it's a shame because in the primary you have the biggest say in who's going to be on the ballot in November," said Julie Lewis, (R) Broome County Legislator.
Democrats will also have the opportunity to participate in the primary process to select their nominee for the presidency.
Polls are open from noon to 9 p.m. in New York, and 7 a.m. to 8 p.m. in Pennsylvania.
