A vast majority of Georgia's incumbent state representatives and senators aren't facing any opposition in their re-election efforts in 2016, according to a breakdown by Ballotpedia.

A total of 80.5 percent of Georgia's legislative contests feature no major party opposition in November, much higher than the national average -- so far -- of 45.8%. Georgia's primary elections are set for May 24, and Ballotpedia found there are 163 Democrats and 223 Republicans running for 236 seats.

"We routinely check our candidate lists because, throughout the year, candidates are removed from the ballot or withdraw from election," said Ballotpedia elections analyst Tyler King. "With a few exceptions we've seen over the years, this generally doesn't impact the overall competitiveness themes in a major way. The number of open Democratic seats was reduced by one because all of the candidates for HD162 are running in a special election. We will consider the winner of that election an incumbent for the purpose of these elections." Republicans hold wide majorities in the Senate (39 to 17) and House (118 to 61, with one Independent).
