New Jersey voters picked their party nominees Tuesday, setting up the fall's general election contests.
The results suggested that the state could be a political battleground in a November election for the first time in a long time. Seven other states also held primary elections Tuesday.
Here is a recap of the results:
Webber and Sherrill will face off to take the seat of Rep. Rodney Frelinghuysen, a moderate Republican and incumbent who announced his retirement earlier this year. Politico reported in January that Frelinghuysen was "caught between the Trump wing of the GOP and a growing Democratic New Jersey electorate."
The 11th District includes Morris County in North Jersey. The open seat, prompted by Frelinghuysen's retirment, led to competitive primaries in both parties.
Van Drew is seen by national Democrats as having a relatively clear path to election to the House in one of several districts in New Jersey that might combine to help Democrats take control of Congress.
Though party strategists say Van Drew is a good fit for the district, some Democrats think he is little better than a Republican. Van Drew has voted against tougher gun laws and same-sex marriage.
Sprawling across South Jersey, the Second supported Barack Obama twice, but President Trump carried it by 5 percentage points in 2016.
Menendez, who survived a federal corruption trial last year after jurors deadlocked on bribery charges against him, won the Democratic nomination Tuesday to seek a third term on Capitol Hill.
He defeated Lisa McCormick of Rahway, 49, publisher of a community news website. She said she ran to give voters "more and better choices" and attacked Menendez for having "disgraced" New Jersey.
Menendez will face Republican Bob Hugin in the fall.
The district will be competitive come November, with Lance considered a vulnerable GOP incumbent.
Welle is a veteran Navy officer and founder of a technology software company. He faced off against Jim Keady, a liberal activist and former Asbury Park councilman most famous for the time former Gov. Chris Christie told him to "sit down and shut up" as he protested the state's response to Superstorm Sandy in 2014.
Welle will now take on incumbent Rep. Chris Smith, a long-serving Republican considered newly vulnerable by the national Democratic Party.
The Fourth includes parts of Ocean, Monmouth and Mercer counties.
Hugin, a millionaire former pharmaceutical CEO, won the Republican primary for U.S. Senate, giving what party leaders believe is a fighting chance in a deep blue state. He'll challenge incumbent Democratic Sen. Robert Menendez in November.
The First, which contains most of Camden County, a sliver of Burlington County and part of Gloucester County, is overwhelmingly Democratic.
The two will face off come November.
Neither candidate was challenged in the primary for the competitive district, which includes most of Burlington County and swaths of Ocean County. MacArthur, for whom Trump held a fundraiser at his Bedminster golf course last summer, and Kim, a former national security adviser in the Obama administration, already have been trading jabs.
Results are beginning to come in across New Jersey. We will update this story with the latest.
New Jersey isn't the only state to hold midterm primary elections today. Seven other states — California, Mississippi, Alabama, Iowa, Montana, New Mexico and South Dakota — are also voting to determine party nominations ahead of November's midterm elections.
A teenager who confronted state Sen. Jeff Van Drew earlier this year about the lawmaker's record of receiving NRA donations tweeted Tuesday that she had voted for one of his opponents —Will Cunningham — in the Democratic primary for the Second Congressional District.
This was the confrontation back in February.
Early reports indicate a low turnout.
Primary voting in New Jersey is typically light. The lowest in recent years came in 2015, when only 5 percent of registered Democrats and Republican cast ballots in races for State Senate and General Assembly.
The biggest turnouts are in presidential election years, with turnout hitting 35 percent in 2008 and 26 percent in 2016, but only 11 percent in 2012.
There are 5.8 million registered voter in New Jersey with unaffiliated voters, numbering 2.5 million, forming the largest bloc. There are about 2.1 million registered Democrats and 1.2 million Republicans.
Two people who came out early to vote, for themselves no doubt, were Jeff Van Drew and Will Cunningham — candidates for the Democratic nomination for what has been a Republican-controlled House seat in South Jersey's Second District.
Van Drew took a moment time to comment on what has suddenly become a hot topic in South Jersey: President Trump's decision to rescind the invitation to the Super Bowl champion Philadelphia Eagles to visit the White House. But his "I was disappointed" statement was low key in comparison to what Democrats in Pennsylvania were saying.
Positions up for consideration include the U.S. Senate seat now held by Democrat Robert Menendez, who is running for re-election, and all 12 of the state's seats in the House of Representatives. Increasing chances that New Jersey will be in position to deliver anywhere from two to five Democratic victories in U.S. House districts now held by Republicans have elevated the state's usually sleepy primary to center stage.
A number of county and municipal nominations are also up for grabs.

Voters must be affiliated with the Democratic or Republican parties to cast ballots in each party's primary. Unaffiliated voters, however, can declare a party affiliation at their regular polling places.
