President of Canada?

In an election where foreign policy might be the number one issue (let's not forget that war is foreign policy) Barak Obama has made another blunder. This one might be small, but it might not. The question is, how rehearsed was his answer? Was it a slip of the tongue or did he actually think that Canada has a president?

The quote on trade aggreements:

I would immediately call the president of Mexico, the president of Canada, to try to amend NAFTA, because I think that we can get labor agreements in that agreement right now. And it should reflect the basic principle that our trade agreements should not just be good for Wall Street; it should also be good for Main Street.

There are several issues with his statement I will list two.

1.) Canada's government, a parliamentary democracy, has a very different form of government from the USA. Up there the figurative head of state is the Queen and the head of the government is the Prime Minister, there is no President. Barak should know this. Should he win the nomination and, subsequently, the election he will be meeting with Kings, Queens, Princes, Emirs, Presidents and Prime Ministers. It would be a good thing if he knew the difference.

2.) It is arrogant of him to think that he will just call up Mexico and Canada and alter agreements that have bolstered the economies of both nations. Canada is to a large degree an exporting nation, it is not in their best interest to "amend" an agreement that gives them relatively free access to the largest import and consumption driven market in the world. Why would they want to "amend" NAFTA? Why would Mexico? To bail out the US whose consumption addiction is now even more devastating than before due to their plummeting currency?

I don't believe that Obama's faux pas will have an effect on the primaries, but should he win the nomination, the merciless Republican machine will have yet another weapon to use to destroy him.
