First,.virtually half the people in the country would start to consider the federal government invalid. From that point it would probably lead to some nasty actions on down the road which would eventually culminate in war and the balkaization of the U.S.A.
It depends who the military will support. I'm sure Obama has enough plants in the higher ranks, to pull it off. Even if people tried anything after that, it would just be mass suicide.
If anything is going to happen it needs to start NOW! Later will most certainly be too late.
