Well, for a guy who was accused for running a bland administration for a decade, Doer certainly made up for that this week !
I will leave the more detailed examination to folks like Curtis, Frog etc. My brief two cents:
On the resignation: In ANY career, the ability to go out while still popular and on your own terms are nice options to have. Doer was able to do both.
On the appointment: Doer has political experience and savvy, the ability to work - and get things done - with a wide range of folks and is generally likable. That's not a bad combination. He's not a foreign policy wonk but I have a feeling that under Harper you'd have one of the shortest leashes of any US Ambassador.
It's nice to have a Winnipeger there - I can't wait to see the Bomber flag flying over D.C. if the Bombers win the Grey Cup !
Good luck Mr. Doer !
