Cain already had begun to lose some of his luster. He changed his 9-9-9 tax plan to a 9-by-9 model. He joked about his lack of foreign policy expertise by claiming he doesn't need to know the names of the leaders of flyspeck countries, such as "Ubeki-beki-beki-beki-stan-stan." Cain told CNN's Wolf Blitzer he could see himself authorizing the release of all Guantanamo Bay detainees in exchange for one captive U.S. soldier. Then he said that he had spoken "in error."
Cain's presidential campaign always was going to tank. Now it's going to tank ugly.
