Incumbent Sen. Tom Cotton (R) secured the Republican nomination with 82% in the March 3 primary, fending off minor challengers and advancing as the overwhelming favorite against Democratic nominee Hallie Shoffner, a farmer who narrowly won her primary. Recent GrayHouse polling shows Cotton leading 58%-36% among likely voters, underscoring his incumbency advantage in Republican-leaning Arkansas, where no Democrat has won a Senate seat since 1996. Trader consensus at 93% for Republican reflects Cotton's fundraising edge, national GOP Senate majority, and state's battleground status limited to deep-red dynamics. Scenarios to shift odds include a major scandal, health event, or unforeseen national midterm wave favoring Democrats before the November 3 general election.
