No, not Paul Martin. Paul Wells.
Wells points to the second example in a week in which Frank McKenna, our newly minted ambassador to the United States, has shot his mouth off and the Prime Minister has immediately had to state in public that McKenna's remarks don't reflect Canada's position. So, as Wells said, (and to repeat the link because I agree that strongly), "Frank McKenna should hand in his resignation."
You'd think we would have learned from the example of Paul Cellucci that ex-politicians don't necessarily make good diplomats.
