In Alaska, Republican Sen. Dan S. Sullivan is set to face off against his Democratic challenger, former Rep. Mary Peltola, on Thursday as he bids for reelection.
The debate begins at 11 p.m. EDT. Watch live from Alaska Public Media, in partnership with Alaska's News Source and KTOO, in the video player above.
The race also features another Republican with the same first and last name as the incumbent. However, Daniel J. Sullivan Jr. will not be on the debate stage, as he did not receive at least 5% of the primary vote required to participate.
The Cook Political Report updated its rating for the race in July from Lean Republican to Toss Up.
