Many reasons - chief that the main stream media plays along with them. Even before the MSM was exempted from McCain/Fiengold they knew which side of thier bread was buttered, and cozyed up to the LIEberals. They know it's all a big lie, but it doesn't matter. They will block NRA paid ads while giving the other side a free ride.
I see another small run, after all, it IS tax refund season. Hmm, so maybe it's yet another lie, and Obama just wants to stimulate the economy again in the black rifle sector...yeah, right!

Time to go get your SA vz-58s while you still can!
