2022 Arkansas Primary Election Results

In the Arkansas primary elections Tuesday, former White House press secretary Sarah Sanders is a front-runner for the Republican nomination for governor.

And two-term U.S. Sen. John Boozman hopes to fend off a challenge from three Republican rivals in a race in which he’s had to rely on his endorsement from Trump as well as the state’s top GOP figures.

The mild-mannered Boozman has taken a more aggressive tone in his campaign ads, vowing to complete the wall along the U.S.-Mexico border.

Boozman’s rivals include former NFL player Jake Bequette, who has the support of a super PAC that’s aired ads attacking Boozman as not conservative enough, and Jan Morgan, a conservative activist and former TV reporter.

Sanders is heavily favored in her Republican primary for governor. She faces a long-shot primary challenge from former talk show radio host Doc Washburn.

Sanders has shattered fundraising records and has focused mainly on national issues, running spots criticizing President Joe Biden on issues like inflation, while ignoring her rivals.

Five Democrats are seeking the party’s nomination for governor, with nuclear engineer and ordained minister Chris Jones the front-runner.

The candidates are running to succeed Republican Gov. Asa Hutchinson, who is barred by term limits from seeking reelection.
