The George Allen versus Jim Webb Senate race in Virginia is as close and dirty as they come. The up-side is that Republican Allen’s bungles— his “macaca” references, his quoting Webb’s war novels out of context, his hired goons beating up bloggers— have generated some hilarious Web material, like this old crackup at ridiculopathy.com and the sad-hilarious YouTube gem sending up his history of racist weirdness. Can this guy, the height of contemporary political disingenuousness, really win? He can but he mustn’t.
