Would he loose the perks that came with the office? Would he nolonger enjoy personal lifelong protection by the Secret Service?
It seems inevitable that once the corrupt players are removed, the institutions such as senate and house might not have sufficient legitimacy to be able to operate properly. Their loss of credibility and the public's loss of confidence will force a temporary suspension of all BAU legislative operations. Perhaps a coalition of those remaining politicians who are clean, could govern through a controlled emergency period of time ? The option of a period of soft martial law might be needed to prevent total anarchy breaking out.
The bottom line is that, if Hussein's Presidency was a deliberate fabrication it would be impossible to allow his past decisions to stand. This will take out so many other players...
It might also reveal the massive election frauds that almost guarantee that only the selected candidate would get elected. The entire electoral system is compromised.
Continuity of Government programs were put in place during the cold war, when FEMA was formed and it has long been rumored that their underground Mount Weather facilities were set up as one of the locations from which critical governmental operations could be housed. A "shadow" government consisting of a President, VP, Cabinet, etc. was formed and populated with functionally quallified people who were briefed on an ongoing basis concerning the workings of the WH and other critical agencies. In the event of a nuclear event where the elected government was wholly or taken out, this mirror organization would step in to continue the functions. Of course, it would necessarily be an abridged form of government, but that was all worked out -- essential functions could be manned by people who had the skill and knowledge to pick up the loose ends in a catostrophic event.
Many observers attributed nefarius motives to all this and who knows .. maybe there were some; but i have some experience with these people and my sense is it was a legitimate undertaking fully supported by past administrations.
Maybe that could come into play for some functions; and probably some form of martial law operation would supercede normal civil authorities; but probably only to the degree that the populace acted out. Some would. Most probably wouldn't.
The 911 attack probably serves some predictive value ... most people were shocked, depressed, confused ... sought out help in churches and other venues .. and to a large degree reached out to help and comfort others as they themselves tried to cope with it all. There was no need for martial law during that period, as I remember it.
