In their first debate, the five Republican candidates for Congress in Georgia's 12th District responded to questions about Obamacare, Ukraine, reducing regulations, and states' rights in regard to medical marijuana. Monday night's debate, first in a series of four organized by the 12th District Republican Party, filled the auditorium at Ogeechee Technical College almost to capacity. Voters in the May 20 primary, and a possible primary runoff, will choose one of them to challenge the Democratic incumbent, U.S. Rep. John Barrow, in the November general election.
