The 1980 United States Senate election in Georgia was held on November 4, 1980. Incumbent Democratic U.S. Senator and former Governor of Georgia Herman Talmadge ran for reelection to a fifth term, but lost narrowly to Mack Mattingly, Chairman of the Georgia Republican Party.
Mattingly became the first Republican Senator from the state since Reconstruction in 1873. This marked the first time that a Republican served a full term in the state's history. This race was part of a landslide national election for Republicans that would come to be known as the Reagan Revolution.[1]
As of 2024, this is the last time an incumbent Democratic Senator lost a bid for re-election while the Democratic nominee for president simultaneously carried that same state's electoral votes.This is also the only U.S. Senate election (as of 2024) in which the Republican nominee carried Fulton County in its current form.
This election was the first time ever that a Republican was elected to the United States Senate from Georgia by popular vote.
Talmadge's ethical issues made him uniquely vulnerable, especially after being censured in 1979. Because Georgia was seen as a strongly Democratic state, five primary opponents declared their candidacies for the Democratic nomination. Strongest among these candidates was Lieutenant Governor Zell Miller. Miller launched his campaign with support from black voters, organized labor, and the liberal wing of the Georgia Democratic Party. He campaigned against Talmadge on the argument that Talmadge had "disgraced" Georgia. Miller also attacked Talmadge's history as a segregationist and boasted of support from black leaders including Atlanta mayor Maynard Jackson and State Senator Julian Bond.[2]
In the six-man primary held August 5, Miller and Talmadge advanced to a run-off election. Talmadge won the run-off election with 58.6% of the vote.
Mattingly was unopposed for the Republican nomination.
