I’m willing to bet that he’s having to do multiple rallies per day just so that people will get a chance to see him.
Other candidates would rent out a HUGE place for maybe 70,000 and have one rally that may or may not fill it, and probably would have to bring along a band or something too.
Trump is reaching more people with a series of huge rallies, and these people just want to see HIM. And Rudy, but mostly him.
Except for Hillary, who can't draw more than 400 supporters for a campaign rally.
