There's also a movement of late among the left to demonize conservative talk radio, apparently in an effort to regulate and censor it. I suspect that some of the more rabid lefties are going to use this attack as yet another "we need to clamp down on talk radio" talking point regardless of who the attacker was and regardless of their motivation.
With that being said, I still hope they catch the assholes who attacked her and send them to jail for a good long time.
