When we think of a debate about public policy, we assume facts, arguments, and logic. But Donald Trump uses none. Last night Trump demonstrated once again that he has a handful of slogans and potted remarks on every subject, which he repeats time and again, interspersed with blather about how wonderful he is. When questioned about anything personal -- his tax returns or a civil lawsuit against him or whatever -- his response is always denial and attack.
But Trump is not really selling public policy, or rational argument, or even rational thought. He’s selling an attitude: that the entire political establishment is rotten to the core, including the mainstream media -- and that America needs a bullying, domineering, plain-speaking, strongman to put things right. So I fear that his awful performance last night won't hurt him in next week’s Super Tuesday primaries.
