Faced with a critical question, Newt Gingrich often responds by criticizing the questioner. Mitt Romney reacts with a kind of gee-willikers frustration.
But Herman Cain, whose problems have transfixed the Republican presidential campaign, has used a different strategy. The businessman often responds to trouble with a flat, short answer: Whatever it is, it isn’t true.
His denials usually come with little or no explanation. When other candidates — not to mention economists — began to find flaws in his “9-9-9” tax plan, Cain responded, “All those are simply not true.”
When allegations of sexual harassment were first raised against him, Cain denied any validity to them. “Totally baseless and totally false,” he said, denying that there was any settlement in the cases.
