State treasurer Alexi Giannoulias called former Chicago inspector general David Hoffman a hypocrite and compared him to Rush Limbaugh during this morning’s forum for Democratic Senate candidates at the Union League Club.

Hoffman shot back that Giannoulias and the bank his family owns engaged in the kind of risky lending that brought down the economy. He also insinuated that Giannoulias is a liar.

Yet the most interesting part of the morning actually came after the debate itself was over.
