Georgia Labor Commissioner Michael Thurmond (D) will vie to become the first African-American elected to the Senate from the South since Reconstruction.

He won the Democratic primary Tuesday to face Sen. Johnny Isakson (R-Ga.) in the November election.

Thurmond defeated Democratic activist R.J. Hadley in the primary, capturing 83 percent of the vote according to unofficial results. The Associated Press declared him the winner. 

Thurmond has been labor commissioner for 12 years, but has raised only $117,000 since announcing his Senate bid in April. Isakson had almost $5 million banked at the end of June, according to his pre-primary filing.

The first-term Republican was thought to be vulnerable in light of his recent health scare.

Isakson, 65, was hospitalized twice in March for what he said was “just a toxic shock reaction to bacteria.”

But he promised to make a full recovery and wage a vigorous reelection campaign.
