What is the sound of one shoe dropping?

Wandering around the blogosphere reading the DeLay fallout. It's clear there's something else pending, but it's actually quite enjoyable when the official rationale behind his removing himself from the race is that it would get too 'nasty'.

Speculate - how bad does the whatever-it-is have to be when you can't even trust Diebold to see you through?

And if a shoe falls in the forest and there's no one around, does it make a noise?
