Regarding "free trade" (NAFTA) between Canada, U.S. and Mexico, it appears that the candidates have very different opinions.

McCain (and Harper, Canadian PM) both right-wingers want to keep it in place.

Hillary wants to open it up and re-negotiate.

Obama is playing two ends against the middle and nobody seems to know what he really thinks about NAFTA.

If the primaries (especially Ohio) have anything to do with the economy, its Hillary who will be able to wade through this mess.
