That seems rather strange when a million tickets were requested. Maybe they were set up. Or maybe it’s partly that the ticket requests were not actually people who wanted to attend, plus all of the scare tactics of the left worked.
Maybe the Iowa Gramma was successful after all:

It could be that the left went on overload getting tickets!! So there would not be enough for his supporters
