Senate President Pro Tem Tommie Williams, formerly the State Senator for the Cracker Squire's senatorial district.

From the ajc's Political Insider:

During the GOP primary runoff for governor between Nathan Deal and Karen Handel in August, Senate President pro tem Tommie Williams of Lyons jumped into the contest with gusto – on Deal’s side.

Which may be one reason you haven’t seen Deal try to protect Lt. Gov. Casey Cagle of Gainesville.
