Democrats Flip Arkansas Senate Seat and Threaten GOP Supermajority

Democratic candidates made significant gains in the November 4, 2026, elections, flipping a state Senate seat and threatening the long-standing Republican supermajority in the Arkansas House of Representatives.

Allison Grigsby Sweatman, a mental health professional from North Little Rock, won the election for Arkansas Senate District 13. Pulaski County election officials reported that Sweatman secured 53 percent of the vote to defeat Republican Representative Brandon Achor. Sweatman attributed the victory to a focused ground game that included knocking on 12,000 doors. In a related race, Democrat Cassandra Mayes defeated Stephen Bright to flip House District 71, the seat previously held by Achor.

Unofficial Associated Press results indicate Democrats are leading or projected to win 10 House seats currently held by Republicans, including Districts 10, 11, 13, 15, 19, 32, 55, 62, 67, and 71. If these results hold, the Republican three-fourths supermajority in the 100-member House—held since November 2016—will end in January. This shift would hinder the approval of appropriation bills, which require a three-fourths vote.

The Democratic Party of Arkansas centered its strategy on breaking the GOP supermajority, while the Republican Party of Arkansas had predicted the GOP would maintain its dominance in both chambers.
