This "right wing" agitprop started last week in an article in a despicable commie rag in England. It has all the earmarks of a DNC/klinton campaign.
My guess is that their focus groups are showing the klintons (there is no DNC outside of Bill and Hitlery) are steadily losing ground, and this is the only course of action that has even a remote chance of succeeding. Hitler blamed everything on the Jews, while Bill and Hitlery are blaming it on the NRA, militia, talk radio, etc. After all, those groups are always suspect, and always in need of being silenced. And they certainly wouldn't want to upset the REAL terrorists among us.
This disgusting campaign of lies, destined to become much louder, is the way the klintons hope to defeat Bush. The fact that it hurts the war effort, and persecutes innocent people just makes it all the more attractive to them.
