How low can they go?

I don't think I can say anything that hasn't already beaten to death on Twitter and in the rest of the blogosphere, but I'd like to highlight something:

Until tonight, no candidate has used graphic images from 9/11 for partisan benefit.

Yes, the fearmongers - especially Giuliani - love to trot out 9/11 as often as they take a breath. But not until tonight was anyone so crass as to use such a vivid portrayal of the awful events of that morning.

That's a new low for American politics - co-opting mass murder to get elected.
