He can't be formally ousted unless he is convicted of a crime. Most politicians, even the severely ethically challenged ones, would resign after even a small percentage of the stuff we have seen with this guy - if only to spare themselves from ongoing embarrassment and ignominy. Not so Mr. Ford, the living proof that sometimes the strict letter of the law is not enough.
To be honest I fully expect him to die in office, probably some kind of appalling ignominious thing like an overdose or while in a drunken brawl at a massage parlor. And I don't expect him to survive much longer - that kind of self destructive behaviour doesn't tend to survive much past 40, and he is pushing the envelope on several fronts.
