They all do debate prep (except for Trump), so much of the time, it's rehearsed. They do have to ad-lib at times, ad some are better at it than others, but they pretty much know what to expect and they're prepared. It's been that way for years.
Trump refuses to prep for a debate, so all you're going to get from him is a word salad - he can't focus. If you saw his interview with Chris Wallace today, you'd know that. He was just making stuff up as he went along. |
