Three more incumbents became official candidates to county-level offices Friday as the first week of qualifying ended.

Central District Constable Randy Naylor and justice court judges Eddie Woods Jr. and Jeff Crevitt filed to run in party primaries Aug. 2. Naylor, 56, and Crevitt, 47, will run as Democrats; Woods, 45, filed as a Republican.

Naylor first won the post of justice court paper server in 2007. The justice court bench, usually buried on the state and county election cycle ballot every four years, appears for the third straight year in 2011. Crevitt won a special election for the office’s southern district in 2009 following the death of his father, and the central district’s James Jefferson won a special contest last year to fill the unexpired term of Richard Bradford. Woods, elected from the northern district, is seeking his third term to the position.

Justice court judges preside over small-claims cases, misdemeanor offenses outside city limits and state traffic offenses.

Offices for governor and lieutenant governor will lead off the ballot later this year, with local races including supervisor and sheriff. District 1 Supervisor David McDonald plans to run for re-election to his county board seat. District 3 Supervisor Charles Selmon filed Thursday. Jefferson and County Prosecutor Ricky Johnson qualified earlier in the week.

Qualifying runs through March 1 for county and statewide races and June 1 for legislative offices. Party primaries are Aug. 2, and the general election is Nov. 8.
