The Obama campaign is caught red-handed spinning (i.e. lying) about comments one of his advisors made to Canadian officials not to take seriously his campaign statements concerning NAFTA.

To Midwestern unionists, Obama criticized the free-trade agreement as unfair to American workers and promised to amend it, while one of his top advisors secretly advised jumpy Canadian trade officials of Obama's insincerity on the issue.

Chances are the mini-scandal won't hurt him in today's important primaries but it could come back to haunt him during a general election should he win the nomination.

It should.
