Reeves, who was first elected in 2019 after serving two terms as lieutenant governor, faces a challenge from Democrat Brandon Presley, a state utility regulator and cousin of rock ’n’ roll legend Elvis Presley. Reeves was elected in 2019 with 52% of the vote, a surprisingly narrow margin in a reliably Republican state.

For the first time, the gubernatorial race in Mississippi is subject to a Nov. 28 runoff if no candidate receives a majority in Tuesday’s election. A potential delay in reporting a final winner may be in determining whether a candidate has cleared the threshold needed to avoid a runoff.

Gwendolyn Gray, an independent candidate, withdrew on Oct. 9, but will still appear on the ballot.
