"Herman Cain offered a unique and valuable voice to the debate over how to reform our country's uncompetitive tax code and turn around the economy. I understand his decision and wish him and his family the best."
"Herman Cain provided an important voice to this process. His ideas and energy generated tremendous enthusiasm for the conservative movement at a time it was so desperately needed to restore confidence in our country. I wish Herman, his wife Gloria, and his family all the best."
"I know this was a difficult decision for Herman Cain, his family and his supporters. He helped invigorate conservative voters and our nation with a discussion of major tax reform. Anita and I wish him and his entire family all the best."
“Herman Cain’s 999 plan got our country talking about the critical issue of how to reform our tax code and he elevated the dialogue of the Republican presidential primary in the process. I am proud to know Herman Cain and consider him a friend. I know from having worked with him for more than a decade he will continue to be a powerful voice in the conservative movement for years to come.”
“I have no doubt Herman Cain will remain a significant voice in the dialogue about the many important issues we face. His rejection of business-as-usual in Washington has been a valuable part of this campaign, and clearly resonates with a great many Americans. I wish him the best.”
"Herman's campaign was one of ideas," Romney said. "His decision was based on what is best for him and his family."
