 "Herman Cain's 999 plan got our country talking about the critical issue of tax reform and he elevated the dialogue of the primary. I am proud to know Herman Cain and consider him a friend and I know he will continue to be a powerful voice for years to come."

Herman Cain brought energy and enthusiasm to the Republican nominating process, as well as a unique perspective on many domestic issues important to voters such as tax code reform and a pro-growth agenda favorable to the private sector.
