There is a distinct Trump pattern that has emerged over the span of his campaign. He accuses others of things that really only apply to him.
Now he is insinuating Hillary Clinton is taking drugs that wear off before the end of the debate. I think this explains all the sniffing Trump did throughout the first two debates. He knows he would never take a drug test before the last debate just like he will never release his tax returns. This guy truly is the king of the deplorables.
