It’s 6 a.m., New Jersey. That means polls have opened on Election Day 2019.

Voters throughout the Garden State on Tuesday will choose the members of the state Assembly and decide a number of other county and local races.

Polls close at 8 p.m. It’s a state holiday in New Jersey, but not a federal holiday. Here’s a list of what’s open and what’s closed on Election Day 2019.

Atop the ticket are all 80 seats in the Assembly, the lower house of the New Jersey Legislature, which passes the state’s laws and decides how to spend your taxpayer dollars in the state budget

Plus, there’s one special state Senate race in South Jersey, as well as a statewide question on whether to give certain military veterans a tax break. Then there’s a closely watched ballot question in Jersey City on Airbnb accommodations.

LEGISLATIVE RACES TO WATCH

STATE SENATE

There’s only one seat up for grabs in the state Senate: to fill the final two years of the South Jersey seat once held by Jeff Van Drew, a Democrat who moved up to the U.S. House of Representatives last year.

Democrat Bob Andrzejczak was appointed to temporarily fill the seat in the 1st District and is now looking to be elected to it. He’s being challenged by Republican Mike Testa.

The district is a tricky one because it’s largely split between Democrats and Republicans.

STATE ASSEMBLY

Democrats hold 54 of the 80 seats in the Assembly — their largest advantage since 1978 — and are unlikely to lose control of the chamber Tuesday. But they’re aiming to add more seats, bolstered by ever-growing voter registration numbers, as well as the unpopularity here of Republican President Donald Trump and Republican former Gov. Chris Christie.

If they add even one more seat, Democrats would have their biggest hold on the chamber since Watergate cost Republicans dearly 44 years ago.

Meanwhile, Republicans are trying to regain some of the seats they’ve lost in recent years and are trying to paint the races as a referendum on Democratic Gov. Phil Murphy, who is now two years into his term. They’re calling the elections “the Murphy midterms.”

Voters pick two Assembly members in each of the state’s 40 districts.

The key races to watch:

1st District

Democratic incumbents Bruce Land and Matt Milam are running for re-election in this politically split South Jersey district, where Trump’s popularity could pose a challenge. Republicans Antwan McClellan and Erik Simonsen are hoping to flip the seats.

2nd District

This is another “purple” South Jersey district in which Democratic incumbents Vince Mazzeo and John Armato are running for re-election and Republicans Phil Guenther and John Risley are trying to sway the district back to the GOP.

8th District

Democrats have been gaining ground in this South Jersey district in recent years, highlighted by how state Sen. Dawn Addiego defected from the Republican Party in January. But Republican incumbent Ryan Peters and running mate Jean Stanfield, a former Burlington County sheriff, are trying to keep the district’s two Assembly seats red against Democratic challengers are Gina LaPlaca and Mark Natale. There’s also an independent candidate running as a “MAGA Conservative,” Tom Giangiulio, who could pull pro-Trump voters away from the Republicans. The GOP is painting him as a Democratic plant.

11th District

Four years after turning this Shore district blue, Democratic incumbents Joann Downey and Eric Houghtaling are running for a third term, against Republicans Matt Woolley and Mike Amoroso.

16th District

Democratic Andrew Zwicker and Roy Freiman are running for re-election against Republicans Mark Caliguire and Christine Madrid in a split Central Jersey district that’s become a battleground in recent years.

21st District

This is the biggest race to watch. Assembly Minority Leader Jon Bramnick — the chamber’s highest-ranking Republican — and longtime district mate Nancy Munoz are running for re-election in a traditionally GOP district that’s been turning bluer lately. They’re facing a tough challenge from Democrats Lisa Mandelblatt and Stacey Gunderman, as well as a pair of “independent conservative" candidates, Martin Marks and Harry Pappas. Bramnick is trying to avoid becoming New Jersey’s first top legislative leader to be ousted at the ballot box since 1993.

25th District

This close North Jersey race got a burst of controversy when Republican incumbent Anthony M. Bucco was selected to move up to the state Senate after the sudden death of his father, Anthony R. Bucco. But it was too late to take Bucco off the ballot for Assembly. He and running mate Brian Bergen face a tough challenge from Democrats Darcy Draeger and Lisa Bhimani. If Bucco wins, the party will pick someone to replace him in the Assembly.

STATEWIDE BALLOT QUESTION

Voters across the state will be asked whether to approve a small tax break for a few thousand military veterans and their spouses in New Jersey.

The ballot question calls on voters to decide if veterans who served during a time of war or other emergency and live in a continuing care retirement community should get the same $250 annual deduction on their property taxes as veterans who live in their own home. The change would cost taxpayers in the state less than $1 million a year.
