Election results you may have missed as you followed the presidential race

Although the race to win the White House dominated Election Day coverage, the outcome of several congressional races could help determine the future success of President-elect Donald Trump's second term.

Republicans have won the majority in the US Senate and now have control of the chamber for the first time in four years. All 435 seats in the U.S. House of Representatives were up for re-election and Democrats hoped they could flip the current Republican majority. According to the Associated Press, 201 Republicans and 186 Democrats had been elected to the House of Representatives as of Wednesday afternoon, while 48 races have yet to be contested.

Key results from the Senate race and why they matter

Democrats held a slim Senate majority heading into Election Day, but three seats were flipped by Republican candidates in Montana, Ohio and West Virginia, giving Republicans a 52-42 lead with six races remaining. As Vice President-elect, Senator JD Vance will now be the Senate's tie-breaking vote.

In Montana, three-term incumbent Senator Jon Tester lost his seat to Navy SEAL veteran Tim Sheehy. Sheehy's victory underscores Republican dominance in Montana, where the party now controls all political offices at the state level.

Republican businessman Bernie Moreno defeated Senator Sherrod Brown for the Ohio seat, becoming the first Latino to represent Ohio in the Senate. It was the country's most expensive Senate election, with both candidates spending more than $324 million on ads in August, tracking firm AdImpact reported.

In West Virginia, Republican Gov. Jim Justice won the seat previously held by independent Sen. Joe Manchin, who did not seek re-election. Justice made headlines after the Republican National Convention for bringing his English bulldog, Babydog, on stage.

Democratic Senator Tammy Baldwin won re-election to a third term representing Wisconsin.

Other notable races that have not yet been called include:

• Arizona: Rep. Ruben Gallego (D) vs. former TV host Kari Lake (R)
