The frontal assault has been underway for quite some time.  Janet Napolitano essentially codified the effort by making it clear Homeland Security recommended viewing returning veterans and "Mom and Pop" Americans exercising their Constitutional rights of peaceful protest as potential domestic terrorists equal to the Islamic jihadists that have cost thousands of innocent American lives.  Not long ago, the far left and their MSM lap-dog helpers were wetting their pants in orgasmic pleasure because they thought the "Times Square Bomber" was a balding white man with tea bags in his pockets.  It's only a matter of time before they either supply, or encourage some nut-case to do something unfortunate they can pin on the Tea Party.
