Why the Obamas lost their licenses
Shaving with Occam's Razor:
Theory #1: Both parties involved in scandal and therefore had their licenses threatened, would be entirely in-character and, as Chrissy details, there is substantial known cause, and who-knows-what unknown for them to have been threatened with losing their licenses.
Theory #2: They were too lazy (incompetent, disinterested, bone-headed) to bother doing the work to keep up the license. Also in-character, needs no other substantiation or cause known or unknown. By his own admission, his biggest fault is laziness.
Occam favors #2, but there's no saying it wasn't a combination of "uh-oh!" and "why bother?"
