I have no reason to doubt you but you have to admit: that is a deadly soundbite. It makes him look positively cavalier about it.
If Huck starts doing well and builds a healthy war chest, that video will be used against him constantly and he will have to explain it to a public with a ten second attention span.
I agree the soundbite is harmful, but I don’t think it is fatal. It was available in 2007/2008 and wasn’t used.
