First a rebuttal to the President's acceptance speech at the convention and now a rebuttal to his 9/11 comments? I think he has officially entered his crash and burn mode.
It's part of the new Leftist political marketing calculus: never give the opponent face tyime that you can't counter. unfortunately for the Left, they still think they aren't "getting their nmessage out", but in fact they are.
And we have seen that, the more their message gets out, the more it is rejected (as evidenced in polling data). Most of them cannot comprehend that their message is being consistently rejected, no matter hoy they package it, repeat it, re-shuffle it. The fact is, most people just want to be positive and free.
