Less than two weeks after his suspension for previous intemperate tweets was lifted, CNN's Roland Martin was engaging in personally insulting "mis-tweetment" again this afternoon with PJ Media's David Steinberg.

In a series of tweets at around 5 p.m. tonight seen after the jump, Steinberg criticized Martin for spending so much time on the press's Trayvon Martin obsession -- where one person tragically died -- while ignoring the impact and meaning of the documents leaked by an unnamed Department of Justice official relating to the Fast and Furious "gunwalking" scandal -- as a result of which "at least 300 Mexicans, plus at least two American law enforcement agents" have been killed. Martin's responses were immature, insulting, condescending -- and all too typical of a press corps which, now that it is seeing poll results it doesn't like, has in certain cases taken to calling voters stupid.

CNN host Piers Morgan joined comedian David Steinberg in mocking the Republican field on Monday night. On his prime time show, Morgan teed up Steinberg to rip the field as a "ship of fools."

On Tuesday morning, the anti-Republican abuse continued on CNN as Muslim comedian Dean Obeidallah quipped that "There are people in the Taliban who would call Rick Santorum a radical conservative. I'm not even kidding."
