Meet the 2021 class of U.S. senators.

Three Democrats and four Republicans have been elected, while others await the results of races still to be determined.

The senators-elect range from a former college football coach to a onetime astronaut to a former governor who opened the first craft brewery in Denver.

Still unresolved are races in North Carolina, Alaska and two in Georgia. Democrats’ path to retaking the Senate majority has narrowed, and control of the chamber could be determined by the races in Georgia, which are both headed to Jan. 5 runoff elections.

A look at the senators-elect:

Tommy Tuberville (R-Ala.)

The Arkansas-born Tuberville, 66, has had a long career in college football, coaching the University of Mississippi, Texas Tech and the University of Cincinnati. In Alabama, he is best known as the former head coach at Auburn. Tuberville, who defeated former senator and onetime attorney general Jeff Sessions in the primary, has called for eliminating the Affordable Care Act, opposes abortion and favors construction of the wall at the U.S.-Mexico border. He stands with President Trump and wants an investigation of the investigators who conducted the inquiry into Russian interference in the 2016 election.

Bill Hagerty (R-Tenn.)

Hagerty is a former U.S. ambassador to Japan. The 61-year-old Nashville businessman left the private sector to serve as the Tennessee state economic development commissioner from 2011 to 2014. He later volunteered as the chair of Trump’s campaign in the state during the 2016 election and was a high-dollar fundraiser for the campaign before joining the transition team.

Lummis, 66, is heading back to Washington. She has spent decades in politics, as a state treasurer and state legislator. She served as Wyoming’s lone congresswoman from 2009 to 2017 and was a founding member of the conservative House Freedom Caucus. She will be the state’s first female senator.

Ben Ray Luján (D-N.M.)

Luján, 48, is a five-term congressman who previously chaired the Democratic Congressional Campaign Committee and was the first Latino ever to hold the job. Luján is a close ally of House Speaker Nancy Pelosi (D-Calif.), who tapped Luján to be assistant speaker of the House. His victory to replace retiring senator Tom Udall (D-N.M.) represents the second time he has followed Udall’s footsteps. Luján ran in 2008 to succeed him in New Mexico’s 3rd Congressional District when Udall ran for Senate. He supports Medicare-for-all, announcing his support for the bill sponsored by Rep. Pramila Jayapal (D-Wash.) bill in 2019.

Mark Kelly (D-Ariz.)

Kelly, 56, the former astronaut and husband of former Arizona congresswoman Gabrielle Giffords, is an ardent gun-control advocate. He took up the issue after Giffords survived a 2011 assassination attempt, a mass shooting that killed six people and injured 13. The pair later started a political action committee, Americans for Responsible Solutions, that pushes for stricter gun-control laws. The organization was renamed in 2017 for Giffords. Kelly, the veteran-turned-astronaut, retired from NASA in 2011.

Marshall, 60, is a two-term congressman who represented the state’s “Big First” district encompassing 63 counties across central, western and northern Kansas. The obstetrician and former captain in the Army Reserve first entered Congress in 2016.
