Another Republican talks about killing Democrats

The talk began during the Sarah Palin rallies on the campaign, when a Palin supporter yelled "Kill him!" about Obama while Palin did nothing, and continues to this day. Remember the Teabaggers marching on the mall, talking about "next time we bring our guns"? Remember the crazy Republicans bringing guns to meeting where Obama was speaking? There is a serious violence and extremism problem in the Republican party. If you or I were to joke about assassinating members of Congress, the FBI wouldn't let us shrug it off as a joke. But this joker talks about shooting congressional Democrats, and it's funny. FOX News' Glenn Beck talks about poisoning House Speaker Pelosi and it's funny.

The GOP is a party rather focused on jokes about murder and assassination. Is this a reflection on the poor caliber of its politicians, or the poor caliber of its voters?
