During Trump's rally on Sunday at Madison Square Garden, his own fans were reportedly "streaming for the exists" while he was still speaking.
The event was so steeped with rhetoric perceived as racist that supporter Meghan McCain said it could "backfire" and cost him the election.
Some of Trump's own supporters may have been fed up with the rhetoric, as well, because many of them were leaving while he was still speaking, according to CNN politics reporter D.J. Judd.

I hope that's the reason, but it's not like he hasn't been saying this for quite some time, just not encompassing the majority of the rally, nor as overtly.
I read he was like 2 hours late to speak, so that may be another reason 🙃
