Nader Says Obama Should be Impeached

I'm not a Nader fan, nor will I ever be, but he makes a good point, if only in his comparison argument. If Bush was to be impeached for war crimes as the left has stated on countless numerous occasions, then why not Obama? Of course, not only has President Obama did nothing to warrant such action (the same with Bush, as everything he did was sanctioned by the Congress-both Republican and Democrat) but I don't see him doing anything in his (God willing) two years left in office to warrant anything like impeachment either. He's not exactly a slimeball like Clinton.
