I have no idea...but the rallies are absolutely good for the campaign - the traditional retail politics is an essential part of victory to get your base turnout, and no one does it better than Trump. But you have to wage the war on all fronts - the people deciding the election are not those going to the rallies but those sitting at home watching their favorite TV shows. And on many media outlets, they are hearing from Harris - and only Harris.

^^^This. The rallies are great, but the number of eyeballs there vs. media outlets ~30,000,000:1.
AND all rally attendees are already Trump voters; the media audience contains potential converts. Much better ROI, IMO.
