JACKSON (AP) — Two Republicans with low-budget campaigns are in a congressional primary runoff today, with the winner set to face Democratic U.S. Rep. Bennie Thompson in November’s general election.

Polls in Warren County opened at 7 a.m. and will close at 7 p.m. This election also features paper ballots as election officials navigate their way through the first election held in the area since the start of the COVID-19 pandemic.

The Republican runoff is between Thomas L. Carey, a retired real estate agent who ran unsuccessfully for U.S. Senate in 2014, and Brian Flowers, a military veteran who works at Grand Gulf Nuclear Station.

Thompson won a 1993 special election and is the longest-serving member of Mississippi’s current congressional delegation. He’s also the only Democrat and the only African American representing the state on Capitol Hill.

Neither Flowers nor Carey has filed a campaign finance report with the Federal Election Commission. Thompson has more than $1.4 million in his campaign fund.

The 2nd District stretches along the Mississippi River, including Vicksburg, through the Delta and into Jackson.

People who voted in a Democratic primary in the 2nd District in March are ineligible to vote in the Republican runoff.
