A member of the Warren County Port Commission and a former school board trustee and the county bridge commissioner face each other Tuesday in a runoff election to determine the Republican nominee for District 4 Warren County Supervisor.

Marty Crevitt and John Carlisle finished first and second, respectively, in the Aug. 4 Republican primary. Wayne Muirhead III, who finished third, has announced he is supporting Carlisle in the runoff.

The winner will face Democrat Casey Fisher, who finished second to District 4 Supervisor Bill Lauderdale in the 2011 election. Lauderdale decided not to seek a seventh term on the board. There are no independent candidates in the race.

The election involves four precincts: Elks on U.S. 61 South, Goodrum Baptist Church on Fisher Ferry Road, Yokena Presbyterian Church on Jeff Davis Road, and Jett at Immanuel Baptist Church on U.S. 61 South.

The party runoff is open only to voters who voted Republican in the first primary. The precincts will be open 7 a.m. to 7 p.m.

Crevitt is a member of the Warren County Port Commission and former hotel industry manager who was appointed by former Gov. Haley Barbour to the five-member port board in December 2011.

Carlisle has worked in a county mobile home business and formerly served as a trustee of the Vicksburg Warren School District. He was nominated to the bridge commission by Lauderdale and approved unanimously.

Crevitt and Carlisle finished the first primary within 28 votes of each other, with Crevitt getting 375 votes, to 347 votes. Muirhead III was third with 221 votes or 23.04 percent.

Fisher defeated Gary L. Cooper in the Democratic primary, winning all four precincts in the Democratic primary, getting 288 votes, or 70.59 percent, to 117, or 28.69 percent for Cooper.
