Perdue, who will face Democrat Michelle Nunn in the November general election, received 55.7 percent to Kingston’s 44.3 percent in Paulding County.
The Republican nominee received 51 percent of the vote statewide.
About 6,880, or 9.3 percent, of Paulding County’s registered voters turned out last week to cast ballots, according to official returns from the Paulding County Elections and Voter Registration office.
Paulding voters also chose Richard Woods over Michael Buck for the GOP nomination for state school superintendent, 52 percent to 48 percent.
The election went to a recount statewide, and the Georgia Secretary of State’s office declared Woods the winner with 50.1 percent of the vote to Buck’s 49.9 percent.
Paulding voters also narrowly chose District 39 State Rep. Alisha Morgan of Austell over Decatur School Board chairwoman Valarie Wilson for the Democratic nomination for superintendent.
Wilson, however, won 54 percent of the vote statewide to win the nomination and will face either Woods or Buck in November.
The position was left vacant when incumbent Superintendent John Barge chose not to seek re-election this year to run for governor.
Most local nominees were chosen in the May 20 primaries.
In the November general election, some incumbents face challengers, including Republican Post 2 County Commissioner Todd Pownall who will face a challenge from Democrat Patti Smith.
District 19 State Rep. Paulette Braddock, R-Powder Springs, will face a challenge from Democrat Sandra Fuller of Dallas; and District 66 State Rep. Kim Alexander, D-Hiram, will face Republican Bob Snelling of Douglasville.
District 30 State Sen. Mike Dugan, R-Carrollton, will face Democrat James Nixon of Douglasville; and District 31 State Sen. Bill Heath, R-Bremen, will face Democrat Charles Winter of Hiram.
