Tony Blair was another 3-termer who lost it completely, again elected not because he was the best candidate but simply because the opposition weren't credible.
I completely agree with a two term limit, would be a great thing to have here although somehow someone would find a way around it.
Granted, nobody has written her a personal apology for the other reasons yet. :-)
(And my opinion, from a Canadian, is that two term limits was one of the smartest things the founders of the US created)
