Glenn Greenwald, who seems from his writing to be both shrewd and decent, argues that at present there is no alternative to the politics of the lowest common denominator:
as the MoveOn vote demonstrated, we have the opposite of a healthy political system, and it is thus far preferable — for reasons I I set forth here — to ensure that a corrupt standard is applied equally rather than allow it to be applied by one political faction against another. Taking the corrupt political tactics wielded by the war-hungry Right and applying those same tactics to them (rather than ineffectively protesting the unfairness of the tactics) is the only way to ensure they cease.
Please persuade me he's not right.
