Actually, it was Howard Dean. The media and others are not supporting HD's assertion. I don't either.
As to the Microphone incident, it will work for DT supporters. For the rest, it will sound like DT is whining. I.e, DT's claim of microphone damaging his debate performance will move more undecided votes to HC if any. Since the debate, DT gave a lot of reasons for the undecided to move to HC and the latest polls are showing the result. And given today's comments from DT (doubling down by going after Clinton affairs), he will lose more women's vote if that is even possible.
