Our latest Mainstream Media Scream features a regular: Chris Matthews, the hard-charging, blunt-speaking host of MSNBC's Hardball. This time he was vilifying the Tea Party senators Ted Cruz, Rand Paul and Mike Lee.

Matthews concluded Hardball on Wednesday, July 31:

"Let me finish tonight with this. They are political terrorists and like all terrorists, including those who use bombs, their number one goal — their only goal — is to blow things up. Cruz, Paul and Mike Lee are on a mission to destroy, shut down the American government, destroy Obamacare, drive the country into default, destroy the U.S. credit rating. Terrorists with one purpose: To bring down, not just this administration but, let's face it, the American government. Just watch. And the fact is, the likelihood out there, is this crew could be the one that crashes the Republican convention next time. And that, fortunately, could be the end of them."

Media Research Center Vice President of Research Brent Baker explains our pick: "Another pathetic tantrum. Matthews must not have much faith in the soundness of his own political views if he keeps resorting to pejorative attacks instead of debating the substance. He's the one 'blowing things up' by using a term which should apply only to mass murderers of the innocent, not to demeaning senators simply trying to enact the policies the citizens of their states elected them to pursue."
