CAFTA Wars: Is the Battle Over Already?

DR-CAFTA, the Dominican Republic- Central American Free Trade Agreement, is facing rough waters in its first Senate hearing, according to this (admittedly anti-CAFTA) report. Opposition is particularly strong in the farm-states, where CAFTA would likely have its greatest effect. Key senators are already suggesting it is heading for defeat.

I am generally supportive of free trade on policy grounds and therefore of these sorts of agreements. But it will be interesting to see if conservatives who support CAFTA pull out the internationalist arguments to defend it, or if liberals switch to nationalist arguments in their campaign to oppose it.
