This week's Mainstream Media Scream features MSNBC's Chris Matthews of Hardball discussing President Obama greatness.

"Is Barack Obama going for it?" Matthews asked on his show. "Is he set on becoming one of the great presidents in history? I'm not talking about Mt. Rushmore, but perhaps the level right below it. I'm talking, to use his word, transformational. And is he using the country's historic demographic shift to do it? Can he combine the new American power of Hispanics and other minorities with the immediate aspirations of women to lob himself into the highest level of presidential greatness?"

Media Research Center Vice President of Research Brent Baker explains our pick: "Given Matthews gets a thrill up his leg whenever he hears Obama's voice, I guess we should be appreciative that he still puts Obama below Mt. Rushmore level. But how many more months before Matthews considers Mt. Rushmore too modest a tribute to Obama?"

Rating: Four out of five screams.
