I've heard from some very smart people that Donald Trump is in very poor health and that he's lying about his condition. I don't know, but look, he's very low energy, he keeps cancelling his rallies. I think we all know. Like I said, some experts have told me these things, I mean look at his hair! That's a very clear sign of something, I think, so I think it's time we took a look at that.
Just about every rally that has been canceled has been replaced with other events.
Trump was in Vegas today. I believe he goes to Washington State for some fundraising tomorrow and is staying on the West Coast (or will be back there) next Tuesday for something in Everett, Washington and then Phoenix, AZ. The Phoenix event that was "canceled" is actually being moved to a larger venue.
Hillary Clinton has nothing publicly scheduled until August 31st in Cleveland.
You can call Trump a lot of things, but a low-energy campaigner is not one of them.
