I agree - about before the election. However, if he loses there WILL be nationwide riots, together with a multitude of court cases that leave the result uncertain, and THAT may lead to some kind of declaration of emergency.
Hogwash. These are intimidation tactics by Obama's thugs. It seems to be working with one immigrant family I know who say they are voting for Obama because they fear that riots will happen if he is not reelected.
I just don't believe there will be "nationwide riots" if Obama loses. However, I would certainly like to test that proposition empirically.
