I feel sure that this is why the RNC was abruptly cancelled and why there have been no more attempts at rallies. There was very likely a credible threat to take out the whole venue with drones, small plane, whatever, and it was just too great a chance.

Would love to see the acceptance speech at Gettysburg but looks like it will have to be the White House. Just keep POTUS safe until this mess is cleaned up and then we can have all the rallies we want.
