Hembree, a Douglasville insurance agent and nine-term state House member, won 48 percent of the vote in a special Republican primary last week. Dugan, a construction company official, received 24 percent of the vote to finish second out of four candidates.
Former Georgia House Speaker Glenn Richardson of Hiram received 15 percent of the vote. Jim Naughton of Carrollton received 12 percent.
Richardson, a Dallas attorney, was seeking a political comeback after resigning his longtime House seat in 2009.
The winner Dec. 4 will face Libertarian candidate James Camp of Temple in a special general election Jan. 8.
The Senate District 30 seat was left vacant after Bill Hamrick was appointed to a Superior Court judgeship earlier this year.
In House District 67, Republican Micah Gravley of Paulding County easily defeated Democrat Leigh McMutry of Winston for the seat.
Gravley won 68 percent of the vote in winning eight of the nine precincts in the two-county district race. He won the district’s three Paulding precincts — Austin Middle, Nebo and Scoggins schools — and five in Douglas County. McMutry won her home precinct in Winston.
The District 67 seat was left vacant when Hembree resigned to run for the Senate District 30 seat.
Meanwhile, Democrat Kimberly Alexander used a strong showing in Douglas County to narrowly defeat Republican Bob Snelling for the seat representing the new Georgia House District 66, which includes part of south Paulding County.
Alexander tallied 52 percent of the vote to Snelling’s 48 percent, according to totals listed on the Georgia Secretary of State’s web site.
A Douglasville resident with strong ties to Paulding County, Alexander won 57 percent of the vote in the nine Douglas County precincts in the two-county district. Snelling won 61 percent in the district’s one Paulding County precinct, but could not overcome Alexander’s Douglas County advantage.
Alexander won in five Douglas County precincts, while Snelling won in four Douglas precincts and the lone Paulding precinct, Taylor Farm Park.
Snelling was seeking a return to the Georgia General Assembly after serving four terms before departing in 2002. Alexander had lost previous races for Hiram City Council and Georgia House District 67.
District 17 State Rep. Howard Maxwell, R-Dallas; District 19 State Rep. Paulette Braddock, R-Hiram; and District 31 State Sen. Bill Heath, R-Bremen, were unopposed for re-election in the Nov. 6 election.
