Here are the unofficial results of New Jersey primary elections held on Tuesday, June 5, including the Democratic and Republican contests for U.S. Senate bids and battles for nominations in several congressional districts that are being closely watched during this key mid-term election year.

At least four of New Jersey's five Republican-held House seats will be in play this fall, aided by strong Democratic recruitment and the unpopularity of GOP President Donald Trump. Nationwide, the Democrats need to win 23 Republican-held seats to take control of the House of Representatives.

Tuesday's primary elections will determine whether the Democrats get the House candidates they want, and which Republicans will be pitted against them in the November general election.

The results below, compiled by the Associated Press, will be updated throughout the night, so please check back later or refresh the page to see the latest tallies.
