I would love to see USA broken up into many smaller pieces. Many of our problems are due mostly to our giant unwieldy scale. Those problems wouldn't be solved by absorbing Canadia.

I'm not opposed to less drastic unions, however. Super-NAFTA? Free immigration? I'd vote for both of those. The thing we should do to help Mexico first is to end drug prohibition. We'll be harshly judged by history, for the violence to which we've subjected the people of Mexico.

Incidentally, many of the pieces into which USA might be broken would end drug prohibition fairly immediately once on their own.
