True, true.
But would, say, a nuke, EMP attack, or something else happening to one or a few major US cities constitute one?
I know, I know....it's some real tinfoil hat stuff. Even so, Obama is Grade-A, U.S. Choice, government-inspected EVIL...and I wouldn't put it past him to initiate a 'false-flag' op.
It’s not tin-foil to game out any of the scenarios you mention. People get paid to do just this. The tin-foil to my way of thinking arrives when belief is not supported by fact. Religion excepted, of course.
An event or series of events happens close to election time - a national emergency is declared - Martial Law. How do you convince all those states, and areas NOT directly affected by those events that they CANNOT hold elections?
It puts a real strain on keeping the lid on things.
So, elections go forward - transition of administrations with Martial Law intact - events contained/analyzed/gamed forward and backward - Martial Law lifted - back to the work of cleaning up the Erkel trainwreck under a newly elected administration. :)
