The primary season is about to wrap up as New Jersey voters get set to head to the polls to pick their party's candidates for president and in 12 U.S. House races.

Presumptive Republican nominee Donald Trump has already sewed up the number of delegates needed to clinch the nomination. Ted Cruz and John Kasich are still listed on the ballot even though they have suspended their campaigns, as the suspensions happened too late to change the ballot.

Democrats will see front-runner and former Secretary of State Hillary Clinton and Sen. Bernie Sanders on the ballot. Clinton could have the number of delegates needed to secure the nomination after results in New Jersey are announced Tuesday.

The congressional contests have drawn less attention, mostly because it looks unlikely any incumbents will lose.

Any New Jersey resident who has not registered to vote will not be allowed to vote in the primary, but can still register for the general election.

A voter who is unaffiliated with a party can vote in the primary by declaring their party affiliation at the voting booth.

Some political polls have shown that some New Jersey voters say that they plan on either not voting or skipping the presidential vote all together because they are unhappy with the choice of candidates.

New Jersey is one of six states holding primaries for both parties Tuesday. The others are Montana, New Mexico, South Dakota and California

Polls are open from 6 a.m. to 8 p.m. Tuesday.
