I've watched a lot of his recent interviews and I do wish he wasn't so long-winded in all his answers, every time. It would be fine to be long-winded on most answers if just every once in a while he'd answer a question with a sentence or two. Change it up, you see. Keep the pace lively and interesting. It's annoying when every interviewer every time has to cut him off to ask the next question. As the viewer, you start to feel like "wow, this guy would just talk for the whole 20 minutes on this one question if they let him".
Excellent candidates for short answers would be topics not central to his campaign and message, for instance the first question on FEMA. Or even topics that are central, sometimes a short answer can be powerful because it's so startling to hear a politician be so direct (e.g. "Would you end the IRS?" "Immediately!"; "What would be your strategy for ending the war in Iraq?" "Just come home. We just marched in we can just come home.")
