Warren County’s longest-serving public officials, one of the longest-tenured county supervisors, the incumbent District Attorney and a first batch of challengers were among entrants into the 2015 local elections this past week.

Constables Glenn McKay and John Heggins filed paperwork by late Friday with the circuit clerk’s office to run for another term. McKay, the northern district constable, and Heggins, of the southern district, both were first elected in 1983.

Constables serve summonses for the justice court system.

Qualifying ends Feb. 27 for local and statewide races to appear on this year’s primary and general election ballot. Primaries are Aug. 4 and the general election is Nov. 3.

District 5 Supervisor Richard George filed his intentions Wednesday for a sixth, nonconsecutive term on the Board of Supervisors. George, 65, was first elected in 1991. He spent the latter part of the 1990s as buildings and grounds chief after an unsuccessful run for chancery clerk. If re-elected, George would be the board’s undisputed elder statesman, as fellow six-termer Bill Lauderdale said earlier this month he wouldn’t seek another four years. George represents southeast Warren County, including the southeastern end of Vicksburg.

McKay, Heggins and George filed as independents.

Filing late Friday as a Republican for supervisor in District 4 was Marty Crevitt, a member of the Warren County Port Commission and former hotel industry manager. Former Gov. Haley Barbour appointed him to the five-member port board in December 2011.

When reached Friday, Crevitt said he would have to step down from the commission if elected.

“I just want to get in and make a difference in the county,” he said. “And control and manage the county assets.”

In District 1, Steven Houston filed as a Republican against incumbent John Arnold, who filed Jan. 9 for a second term.

Houston, a retiree of the Air Force and 30-year county resident, cited a need for better roads and bridges for his first foray into politics.

“I feel I can make an impact on a more smoothly-run system in that area,” Houston said when reached Saturday.

Joining the race for justice court judge in the central district is Henry Phillips, who is challenging incumbent James Jefferson. A former Naval officer and educator, Phillips ran unsuccessfully for the central district post in 2010.

District Attorney Ricky Smith filed to run in the Democratic primary for a third term. First elected in 2007, Smith, as 9th Circuit District Attorney, handles criminal cases for Warren, Sharkey and Issaquena County.

In addition to 24 county and district races, eight statewide offices appear on Warren County ballots this year, including governor and lieutenant governor. Two multicounty district races on the ballot this year are for the Public Service Commission and Transportation Commission. Each elect northern, central and southern district commissioners.
