Some people think he made some kind of deal to resign in lieu of facing jail time. I sure hope that's not the case. Someone who was so brazen about morality and put people behind bars for the very crime he committed while holding an office of public trust needs to spend time in prison.
I was just watching a show about these hypocrites (Spitzer, McGreevy, Craig, Foley, etc.) and I'm just thoroughly disgusted with these fools.
