The last episode of “Now” on PBS with Bill Moyers hosting devoted half of its hour to the Vast Right-Wing Media Conspiracy theory. For a feint toward balance, Moyers interviewed Richard Viguerie on his new book about the alternative conservative media. But he also plugged David Brock and his book “The Republican Noise Machine.” Lots of clips of Rush, Sean, and Mark Levin. A nod to the meanies at Swift Boat Veterans for Truth, and a nod to the bias artists at Sinclair. (He also started with references to Mein Kampf — Moyers, always subtle.) Personally, I whooped to see Rush Limbaugh footage from the MRC’s Oliver North Roast way back in 1990.

In short, a hilarious finish, suggesting that somehow, CBS making stuff up about Bush, ABC writing memos insisting Bush be exposed as a bigger liar, and NBC framing the letters “ILIE” of “FAMILIES” next to Bush means nothing. There is apparently no partisanship in the liberal media, only in the conservative media. Moyers made regular references to the terrible misinformation spread by right-wing outlets, but only two real claims surfaced: that Fox allowed Peter King to misquote Kerry from a 1997 edition of “Crossfire,” and that a Harris poll found 41 percent of Americans believed Saddam Hussein had a role in 9/11. Once again, Moyers offered no proof that Sean, Rush et al were in the habit of blaming Saddam for Mohammed Atta. A typically shabby farewell. But then, I don’t think Moyers is really going away. I’d expect to see more of him on

TV than you’ll see of Rather or Brokaw…
