I don't get it

One big question I have about last night. Since when has Clinton become the anti-NAFTA candidate? After all, it was her husband who went to the mat to push it through Congress, and both he and Hillary supported it and similar agreements throughout Bill's presidency.

Yes, I understand there was this recent flap about Obama and the Canadians, but it seems to me that the Canadians have said there was nothing to that. Of course, the US press doesn't seem to want to hear that -- they want the Hillary-Obama fight to continue. It's gets attention. But, was that big enough and did enough people hear about it to really make the difference? I just don't get it.
