As the United States awaits a winner in the presidential race between Democrat Kamala Harris and Republican Donald Trump, polls have closed in six of the seven closely fought battleground states expected to decide the election.

In the race for Senate control, Republicans picked up a crucial win in West Virginia, deadlocking the chamber in a 50-50 split, for now. With Republicans heading into Election Day with a razor’s-edge lead in the House, majority control in that chamber will come down to just a handful of races.

Trump won Republican-leaning states including Florida, Alabama, Mississippi and Texas, while Harris won a swath of New England and the Northeast including New Jersey and New York.

Meanwhile, attention is gravitating toward the Eastern battleground states of Georgia, North Carolina and Pennsylvania.

GOP sees House gains in North Carolina

Republicans have picked up three seats in North Carolina that were redistricted by the state’s GOP-controlled General Assembly.

Republicans Addison McDowell, Brad Knott and Tim Moore all won seats that were previously controlled by Democrats.

The victories give Republicans an early and potentially crucial boost in their bid to keep control of the House.

But redistricted seats are not all favorable to the GOP. Democrats are hoping to pick up a seat each in Louisiana and Alabama thanks to redistricting.

Montana could be linchpin in race for Senate control

Republicans have banked their bid for a Senate majority on defeating Sen. Jon Tester in red-leaning Montana.

There have been no surprises in congressional races so far, but polls are closing in the Treasure State, as well as in Arizona and Nevada.

Democrats are hoping to somehow run the table in all three states.

In Montana, Republican Tim Sheehy, a retired Navy SEAL and businessman, is looking to flip the only statewide office that Democrats still hold there.

In Nevada, Democratic Sen. Jackie Rosen is trying to win reelection over Republican Sam Brown. And in Arizona, Democratic Rep. Ruben Gallego is looking to make the leap to the Senate over Republican Kari Lake.

What to watch as polls are closing in Nevada

Results could take a while since the state doesn’t release anything until the last person in line has voted. First updates usually include mailed and early votes. The state will add mailed ballots that arrive through Nov. 9, and these have gone strongly Democratic in the past. In recent elections Nevada has added more than 15% of its vote after Election Day. In a closely-watched Senate race, Democratic incumbent Jacky Rosen is facing Republican Sam Brown

Hours extended at nine precincts in eastern Arizona county

A judge has ordered polling places to remain open two extra hours in nine precincts in an eastern Arizona county after a rocky start to Election Day that included malfunctioning equipment and a lack of printed ballots.

Apache County Superior Court Judge Michael Latham agreed to keep the polls open at the request of the Navajo Nation, which filed a lawsuit asking for extended hours due to the problems.

Meanwhile, bomb threats to polling places at schools in neighboring Navajo County prompted some to close momentarily and one to evacuate and send students home for the day.

Authorities said they received email bomb threats at four locations in Navajo County, including at least three polling sites. They determined the threats were not credible.
