Nonsense. This was stuff of conspiracy theories that would have been ridiculed here and assumed to be Democrat propaganda or something that came from a Michael Moore movie just a few months ago. The only reason it gets any support now is because most Trumpsters will believe or echo anything he says.
It's starting to become difficult to tell the difference between Trumpsters and paulbots. If Trump started babbling about water fluoridation and chemtrails I am believe a sizable chunk of Trumpsters would find a way to excuse or support said comments.
I have never bought the official line on 9/11, nor have I bought the conspiracy theory BS. The truth is somewhere in the middle and these sorts of tragedies always go back to gross incompetence on the part of TPTB.
Bush dropped the ball before he picked it up and spiked it in Iraq.
Trump is careful to keep the right amount of ambiguity in statements like that. He would point out the drawbacks of flouridation, then let the media run wild stories about Dr. Strangelove, then point out that scientifically his statment was correct. It's all about the free publicity and securing the anti-liberal vote.
Think about it this way, the more the New York Times attacks him, the more the average Joe likes him.
