Well for one, he walked right into an internet hoax yesterday, it should have been checked and vetted before he posted that fake crowd stuff.
I haven’t seen anything definitive one way or another on whether that was a hoax or not, but we all know Kamala’s crowds are being exaggerated. They’re using a combination of grifting off the draw from musical acts to paying people to show up. That’s worth commenting on.
As with many “outrageous” claims Trump makes, they have the effect of starting a conversation about a topic the media refuses to cover. In the media’s desperate attempts to disprove his claims, they end up highlighting them instead and more often than not, they’re the ones who end up being discredited, not Trump. Trump has been using that tactic ever since he entered politics, and to great effect.
