There have been nasty allegations against Blagojevich and while apparently leaked - alleged recordings. I've not heard an actual audio of his voice but that doesn't mean it didn't happen. In the current state of the political world he is probably tainted, but certainly not the only one.

I admire his tenacity and going forward with his plans in the face of adversity. Were it that serious maybe he should have been arrested or maybe a swat team should have busted into his house as if he were poor.
Until then the job he was elected for continues.
