When a Boston TV reporter pulled a pop quiz to see if Governor George W. Bush could identify a number of heads of state (India, Pakistan, Chechnya, Taiwan -- he at least should have known the first and last given their global importance) in November 1999, Democrats trumpeted Bush's failures to ID them as evidence that he was incompetent to handle American foreign policy.
Answer this: who is the President of Canada? According to Barack Obama, there is one.
In reality, there isn't -- Stephen Harper is the Prime Minister and head of government, there is a Speaker who is the presiding officer of the House of Commons and a second Speaker who is the presiding officer of the Senate. The head of state is Queen Elizabeth II of the United Kingdom of Great Britain and Northern Ireland.
No President there.
And Obama wasn't conversing about a head of state half a world away but the head of our closest neighbor.
