Trump is Coo-coo for Coco Puffs.

It's funny how he didn't hear the question that he repeated back to the interviewer with perfect accuracy, twice.

If this doesn't tell you Trump will say anything for votes, what does?

I think the real reason he didn't answer the question is that he didn't understand "unequivocally disavow" - those are pretty complicated words. Trump might have thought that saying "yes" would mean he supports them. If the interviewer had said "Mr Trump, do you feel the KKK is very bad?" then perhaps he'd have been able to answer. Of course, he can't actually SAY he didn't understand the words, so it's the obviously bullshit "bad earpiece" excuse to the rescue.

That's not to say that I think he's not a racist, as that also seems probable. In this instance however, I think it was more stupidity to blame than malice.

If 'unequivocally disavow' are 'pretty complicated words' to Trump, he's completely unqualified for office.
But he actually asked him to 'unequivocally condemn' Duke, not 'disavow', then went on to dumb it down farther and said 'and say you don't want his vote, or the votes of white supremacists'. Trump replied clearly that he knows nothing about David Duke or white supremacists, so he won't even discuss them. The Duke part is a blatant lie, he's publicly condemned David Duke in the recent past. Condemning or not condemning white supremacists requires no additional information, unless you simply don't know what white supremacy is, which in itself is also a disqualifier for any high office.
At the time of the interview, there was no problem with him understanding anything or bad communication/equipment, only later when his answer bit him in the ass.
I knew that at some point this catch 22 of either being caught agreeing or disagreeing with blatant racists and white supremacists would catch up with him, because taking either stance alienates 1/2 his supporters and makes him lose the election.
