It was to hype big numbers, once rally hit, less people would show so MSM could say that President Trumps actual fanbase and support isnt what it seems. That and if 100k showed up, well that isnt the 1million that was stated ti the media/by the media.
It was a way to get out in front and only wag to deal [them] a blow would have been 1.25 million showing up to smash [their] number.
Gas lighting.
