The 'President' of Canada

In answering a question about NAFTA, Obama said he would call the presidents of Mexico and Canada on his first day in the White House to get labor provisions into NAFTA.

Sen. Joe Biden (Del.) was next and made clear that it was the "prime minister" of Canada not the president, flexing his foreign policy credentials.

Did others notice? And is it part of the broader storyline about Obama's familiarity with foreign policy?

Kucinich said he would call both countries (did he say "president" of Canada too?) during his first week in office to inform them the United States would withdraw from NAFTA and then he would call the WTO and withdraw from that organization. That fired up this labor union crowd.
