Gov. Brian Kemp scheduled a special election for Jan. 31.
Watson’s district is within Senate District 11, which will also have a special election Jan. 31 to replace state Sen. Dean Burke, a Bainbridge Republican. Burke resigned earlier this week to become the Department of Community Health’s new chief medical officer. His resignation will take effect Dec. 31.
Watson announced Friday that he will run for the soon-to-be vacant Senate seat.
Watson, a farmer, was first elected to the House in 2012. He serves as chairman of the House Appropriations General Government Subcommittee.
