You have not learned from NAFTA. Big business wants something badly they will get it even if there is a Democrat President and Democrat Congress. Clinton pushed for NAFTA and a Gringich Congress plus enough Dems pressured by Clinton ratified the agreement (despite the polls showing 65 percent of Americans and many were union dems were against NAFTA). Immigration is even easier to pass with GWB support and Dem controlled Congress. Big business wins again.
