I'll try to be very quick.
It's been certainly a different negotiation, and some would say it's not been a real negotiation at all.
As you mentioned, we are running into, I think, the short strokes of getting an agreement finalized. We do have the constraints of the Mexican election on July 1 and, as you mentioned, the U.S. mid-terms that are coming up. Ambassador Lighthizer has been clear about May being the opportune time to get a deal in principle done.
I'm not sure that if something doesn't get done, it means the agreement is over with. I think it means that we get into this whole period of a “zombie NAFTA”, as it's been called, where the negotiations are in limbo until things settle down both in the U.S. and in Mexico.
There is a desire, though, to get this agreement before the current U.S. Congress; I know that.
