Magats and right wing groups are buying the only tickets to this trying to make it look like it is being supported but then they cannot give the tickets away.
Years ago an analysis of Political books was done, and they could not find one single Right Wing book that was a best seller based on organic buys. They all got there via bulk buys via Right Wing orgs who would then put them in gift bags at events to give them away.
Correspondingly this did not exist on the left at all where, yes they also had bulk buys but also had the organic individual buys to qualify.
They determined it was not because there was no interesting authors or material on the right but because people on the right truly do not read.
