Incumbent Republican Sen. Tom Cotton holds a commanding lead in the Arkansas Senate race, reflecting the state's deep-red status where no Democrat has won a Senate seat since 1992 and Donald Trump carried it by 28 points in 2024. Cotton cruised through the March 3 Republican primary with 82% of the vote against token opposition, while Democratic nominee Hallie Shoffner, a farmer with limited fundraising ($1.6 million raised vs. Cotton's $12.8 million as of late April), advanced with 78%. A February GrayHouse poll showed Cotton at 58% to Shoffner's 36%, aligning with all forecasters rating the race Safe Republican. Absent a major scandal, health issue, or national Democratic wave, trader consensus prices a Republican hold at over 90%, with resolution upon the winner's swearing-in for the term beginning January 2027.
