Judah, using unbridled hyperbole to try to make a point rarely enhances a
discussion. AF1 movement TFRs do NOT shut down "...the entire southern half
of the US...", as you twice posited. As a general rule, they proscribe a
particular route, but then only "...unless otherwise authorized by ATC...".
X miles before and after passage, other traffic will be allowed to cross
paths. You do, in fact, have a TFR that follows the aircraft (as long as
everything runs smoothly); a moving bubble of airspace kept clear for the
passage of AF1.
