Greenwald: Liebermann = McCarthy

Joe Liebermann long ago renounced any pretensions to humanity, intelligence, and decency. Apparently, his little transaction yesterday with Gen. Petraeus pushed Glenn over the edge:

To Joe Lieberman, anyone who opposes whatever Iraq plan he happens to be currently favoring is a frivolous, defeat-hungry traitor -- giving "some comfort" to the "enemy." He's really the Senate's modern-day Joe McCarthy, smearing everyone's character and impugning everyone's motives who doesn't march faithfully along behind the President. What makes it all the more deceitful is that he never ceases to piously masquerade around as the Beacon of Civility and Honor, a disguise long propped up by an adoring Beltway media. But now, Lieberman's behavior has become so toxic and ignoble that even decorous, restrained Senate Republicans -- no strangers to the art of the political smear -- have begun condemning him in unusually strong terms. What is more pernicious than for a politician, in a Senate hearing with the country's new top General in Iraq, to expressly equate disagreement with their war views with treason? Not much.
