Kelly, a Democrat, will face Republican incumbent Martha McSally, who was appointed to McCain’s seat after initially losing her Senate race to Kyrsten Sinema. Arizona is likely to be a battleground state for 2020 as Democrats attempt to regain control of the Senate and Republicans try to retain their majority.
