Obama wins, the lefties have a lootin' shootin' "victory celebration."
Lock and load at sundown November 4.
The difference being if he wins, it will probably be their own neighborhoods they'll be trashing, along with the odd piece of public property, like police cars, buses, etc. But if he looses, when he looses, they'll have other targets for their rage.
Fortunately, many of those other targets are armed to the teeth, and then some.
