Ford

Ok, now, i don't mean to beat a dead horse or kick a guy when he's down but Ford pardonded Nixon.

I know we're supposed to say nice things about him now that he's dead but c'mon.

So say the vice president has to resign over corruption charges. There's a new vice president picked. Then the president has to resign over corruption charges. The the new vice president becomes president and pardons the old president. I'd say the new dude was just as corrupt as the lot of 'em, wouldn't you? Just a hypothetical situation for you to mull over.
