That is definitely the big point. With a 20K venue capacity, most all who hope to attend must expect to be outside IF they even get a ticket. 1m people is about 9X the number of people who attended POTUS and Modi rally in the worlds largest stadium in India. No way to accommodate that many people at one rally. If the city and state Dem forces succeed in preventing the rally, they will get all the eternal blame by 1M local people. If the rally proceeds, only what, 50k people will actually be allowed in and around the venue? 950K would not get a ticket, disappointed but understanding, Trump will be blameless. Trump wins no matter what the Dems do.
