This is stupid, the Trump campaign should not get into making specific medical assertions and diagnoses. Raise observable issues, sure, but no one has any business trying to play doctor on TV without all the medical facts. This can backfire big time.
But if the media goes ballistic on this one, guess what? The public learns there's a controversy about Hillary's health.
If the press are willing to go there, Trump wins because the issue is raise and the MSM follow where it all leads.
There have been countless times in this campaign where the hyperbole created a push-back and that media push-back exposed facts that the public became conscious of.
