I will be curious over the coming days and next week to see how the non-engaged public view the debate. We’ve obviously got strong opinions here on FR, and the media is doing their spin, but this is the first time the American public has seen all of the candidates, less Trump, and it will be interesting to see how that settles out.
Besides showing voters the candidates' opinions and abilities to respond to uncomfortable questions and communicate, in many cases the event is an introduction to the candidates about whom they know little.
As an aside, over the years, I've learned much from televised debates, both parties, including some between-the-lines observations. Hillary comes to mind as unable to conceal completely her true (and scary) self. Willard as a snake-oil salesman. And more recently, Asa as a smiling lightweight.
