Conservatives love to claim that media are systematically biased against them. Indeed, Fox News is based almost entirely on this premise. But the right should be pretty pleased with the major Sunday shows’ pre-Election Day roundtables (via Mike Allen):

— NBC’s “Meet the Press”: Mayor Cory Booker (D-Newark), MSNBC’s Joe Scarborough, Republican strategist Mike Murphy, NBC’s Savannah Guthrie and NBC’s Tom Brokaw

— ABC’s “This Week”: ABC News’ George Will, ABC News’ Cokie Roberts, National Journal’s Ron Brownstein, Democratic strategist Donna Brazile and ABC News political analyst Matthew Dowd

— CBS’s “Face the Nation”: Harvard University’s David Gergen, National Review’s Rich Lowry, Vanity Fair’s Dee Dee Myers and Wall Street Journal columnist Peggy Noonan

— ”Fox News Sunday”: Fox News’ Brit Hume, former Howard Dean campaign manager Joe Trippi, former Bush White House senior adviser Karl Rove and The New York Times’ Jeff Zeleny

You’d think that the Sunday shows would be particularly sensitive to “balance” the weekend before Election Day. Instead, NBC’s roundtable has two conservatives (Scarborough and Murphy) and one liberal (Booker). ABC has two conservatives (Bush-Cheney ’04 chief strategist Dowd and The Post’s own George Will) and one liberal (Brazile). CBS has two conservatives (Lowry and Noonan) and one liberal (former Clinton press secretary Myers). And — stop me if you’ve heard this before — Fox has two conservatives (Hume and Rove) and one liberal (Trippi). As Eric Alterman says, “What liberal media?”
