MOULTRIE, Ga. — The upcoming primary election’s only Saturday voting day will be this weekend.

Early voting started April 30, Monday through Friday, in Room 201 of the Colquitt County Courthouse Annex, but voters will be able to cast an early ballot 9 a.m. to 4 p.m. Saturday, May 12, at the same location.

It’s the only Saturday the office will be open for voting in this election.

On Election Day, May 22, voters can cast ballots at their normal precinct.

Colquitt County Probate Judge Wes Lewis, who serves as the county’s elections superintendent, said as of midday Thursday, some 458 people had cast early ballots.

Colquitt County has three contested races:

• Denver Floyd Braswell is challenging incumbent County Commission Chairman Terry Clark for the Republican nomination for Clark’s seat. This race is only on the Republican ballot. The winner will face no opposition in November’s general election.

• Charlton Tyler is challenging incumbent Patricia Anderson for her Board of Education seat. Only voters in District 5 will cast ballots in this race. The race is non-partisan, which means it will be on both the Republican and Democratic ballots in the district. The winner will be decided during the primary and the race won’t be on the ballot in November.

• Voters in District 1 will choose among five candidates for the Democratic nominee for the district’s County Commission seat. Barbara Jelks recently won a special election to fill the seat through the end of this year. She will compete against Jeron Bridges, Darius Dawson, Susie Magwood-Thomas and James Weeks for the Democratic nomination. Stacey Williams is running without opposition to be the Republican nominee and will face the winner of the May 22 Democratic Party primary in the general election in November.

Two other county commissioners, two other school board members and the chief judge of Magistrate Court are running without opposition.

Several state offices are on the ballot. Contested Republican races include governor, lieutenant governor, secretary of state, commissioner of insurance, state school superintendent and Public Service Commission (one of two seats has opposition). Contested Democratic races include governor, lieutenant governor, secretary of state, commissioner of insurance, state school superintendent, commissioner of labor and both Public Service Commission seats. Republican winners will face Democratic winners in the November general election.

Races generally require a majority — 50 percent of the voters plus one — to win, so any of several races with more than one candidate could go to a runoff. If so, the runoff would be held July 24.
