The middle Tweet came from the desk of John Cobarruvias. The Houston, Tx Democratic Precinct Chair, blogger and member of the Texas Democratic Executive Committee backtracked after the backlash: “My apologies to those I offended concerning the#nra. My emotions on the subject got the better of me. It didn’t help.” Yes, well, his Twitter page still calls the NRA a “domestic terrorist organization” and contains a link to the names of all the politicians who received money from the National Rifle Association. And the left howled when Sarah Palin’s Facebook page put a reticle over the towns where Tea Party activists should “target” vulnerable Dems. Oh, how they howled!
