We all got screwed.
Blago’s as dirty as all of the rest of them and has absolutely no business in public service, but he also got screwed. The investigation was based on wiretaps (a LOT of wiretaps), and only the incriminating ones were introduced. The investigation stopped short of him committing a crime, and the Senate voted unanimously to convict him and, not coincidentally, end all further investigation into the pay-to-play way of doing business in Chicago.
His semi-boycott of the proceedings was a lame move. I’d have preferred him to get badgered by the prosecution, and then turn around and start naming names in his own defense.
They impeached him for soliciting political contributions in exchange for official actions. Votes in the Legislature are official actions, no? I wonder how many of his accusers would pass that test.
