“I’m running as a conservative reformer,” said state Sen. David Shafer, now in the late stages of a Republican primary campaign for lieutenant governor. Interviewed Wednesday in Statesboro, he cited accomplishments during his more than 16 years in the Georgia Senate, which included five years in the leadership as Senate president pro tem. “You know, I authored the constitutional amendment that the voters approved in 2014 that put a cap on the state income tax,” Shafer said when asked about taxation.
