When Georgia's General Assembly convenes in January, Representatives Ellis Black and Amy Carter will be part of the Republican Caucus.
Formerly conservative Democrats, they both cite switching parties as a way to align themselves with Speaker of the House David Ralston.
"In the process of working the change, putting together his team, it's going to be leading the house and I had to make a decision to be part of it or pass the opportunity up, and so I'm on board," said Black.
Representative Carter declined to be interviewed on-camera.
But in a statement to WCTV, she describes her decision as being in the best interest for south Georgia.
She says, "I have consulted with a variety of my constituents and feel this is the best action for our district. Please know that I do not make this decision lightly."
