PHOENIX (AP) – Retired astronaut Mark Kelly, who became a prominent gun-control advocate after his wife, former U.S. Rep. Gabrielle Giffords, was shot in a failed assassination attempt, announced Tuesday he will run to finish John McCain’s last term in the U.S. Senate.

The Democrat will take on Republican Martha McSally in what is expected to be one of the most closely contested Senate races of the 2020 election.

Kelly described himself as an independent-minded centrist who will take a scientist’s data-driven approach to solving problems such as climate change, wage stagnation and health care affordability.

“You see a lot of partisanship in Washington and a lot of polarization, and to some extent we’ve created that,” Kelly told The Associated Press. “It’s going to take people who are more independent to fix it. Arizonans value independence.”

If Kelly is nominated the race would pit the Navy veteran and astronaut against McSally, a trailblazing Air Force pilot, in the contest to replace McCain, a legendary Navy flyer who was famously shot down and held captive in North Vietnam.
