If he declares Martial Law he may be announcing the start of a Civil war.
Hussein is not an American in any sense, especially culture, and I seriously doubt that he understands the psyche of the Country. He might be in for a very rude surprise.
That is a joke, with what Army? Martial law on 300 million people?
We're already in a state of civil war. Most Americans simply refuse to recognize that fact.
The rest, absolutely refuse to consider that the tree of liberty is dry and withered and have no plans to refresh it - because that would take risk and work none are willing to expose themselves to. There is NO EXCEPTION in all human history - that when a government and ruling class of people DEMONIZE a specific group of people, that government ALWAYS criminalizes and then eliminates that group.
And by "eliminate" I mean KILL - as in genocide, cleansing, etc. All done under the color of law.
Obama WILL default - and then decree the government stop paying it's bills so as to maximize pain on the people and get them to turn en masse against the Conservative Tea Party movement and applaud any 'emergency powers' he claims in order to 'restore things to normal'. You just watch. The GOP Ruling class has already greased his skids towards criminalizing the TEA Party.
They just need an excuse. Default may give Obama what he wants - justification to do what he has really intended.
