The question is not whether the left can succeed in a coup, it is whether the right will be forced to try one. The jury is still out on that one.
It does appear that zer0 is attempting to co-opt certain elements including vital industries along with the ability to lockdown the internet and the new media. No doubt he would attempt to gain the degree of control he thinks necessary through some sort of crisis.
I think that ultimately his biggest obstacle will come in the form of states and governors who have already bowed their backs at certain of his proposals. It will be much more difficult to control all 50 states many of whom have already taken steps to voice their displeasure than to control a more homogeneous political entity. To move all the states in the same direction would be like herding a bunch of cats. It’s not as simple as Chicago.
Obama rose in politics through the thoroughly corrupt democrat party and the sheep love it.
The Chavez playbook will do very nicely for Obama for his first two terms. In the second term, he will borrow a page from Zelaya and Chavez, and create a movement to beg "Dear Leader" for a third term. If they can't get an amendment, they will phony up some argument that will allow him to get that third term. Once he is in for life, more and more people will fall in line.
He knows he can't push too hard, or the military and the American people will rise up. So he will spend 8 years destroying the military, putting his people in place, and creating his thug armies. In 8 years, all the teenagers that grow up under him will be young 20 somethings who have never learned about the Constitution, and Obama is all they know. Conditions will be better for what he wants to do. I can hear it now: "The polls say 60 percent want Obama to stay. This is a democracy, isn't it"? He can be stopped, but the window of opportunity is narrowing.
