So, McCain thinks supporting NAFTA is important because Canada has troops in Afghanistan. http://news.yahoo.com/s/ap/20080301/ap_on_el_pr/mccain_nafta So, we shouldn't think about renegotiating NAFTA because Canada has 2500 troops in Afghanistan? Is McCain crazy? I know the guy claims not to understand economics, but I had no idea he really just didn't get it at all. Trade with Canada isn't important because Canada has a few thousand troops in Afghanistan, trade with Canada is important because CANADA IS THE LARGEST U.S. TRADING PARTNER. $561.55 billion combined exports and imports in 2007. http://www.census.gov/foreign-trade/top/dst/2007/12/balance.html McCain should be ashamed for making this argument. It's got to be the stupidest thing I've ever heard.
