In a statement, National Republican Congressional Committee Chairman Pete Sessions thanked Davis for his service, including his work with the House GOP's campaign arm.
"As an NRCC Regional Chair for the 2010 and 2012 cycles, Geoff played an important role in helping us win back the Republican Majority to retire Nancy Pelosi as Speaker," said Sessions. "Geoff is a dear friend, and I greatly appreciate his hard work and will to win for Republican solutions for America."
Republicans are expected to easily hold onto the solidly Republican Northern Kentucky district, where Sen. John McCain, R-Ariz., took 60 percent of the vote in 2008. Early potential successors, according to a Kentucky GOP operative, could include 4th District GOP chairwoman and state Rep. Alecia Webb-Edington and state Sen. Damon Thayer.
