I started to, and then turned it off when I heard the first question.
Therefore, I have no opinion on who "won" the debate.
Besides, I can't stand the after session where the talking head tells me what they just said, what they really meant, and then hear the talking head's opinion of what they said and what it meant.
If they aren't speaking in plain English (and I suspect President Trump did), then they have no business up there debating in the first place.
Plenty of others will have their opinions, and I'm sure the video will get sliced-and-diced for all manner of reasons.
