Yep, bipartisan....
Bush 1 created NAFTA with FAST TRACT abilities, and Bush negotiated and signed NAFTA with Canadian PM and Mexican president in Dec of 1992...
Clinton agreed with Bush that he would sign the treaty of NAFTA when he became president if it was passed.
When Clinton took office, he was not happy with the way NAFTA was written and needed to modify it, in order to get any Democrats to vote yes for it, so Clinton negotiated an amendment to the original NAFTA, making it more palatable for Democrats to vote yes and got Canada and Mexico to agree, then Congress and the Senate passed it with more Republicans in both houses voting yes than Dems.
I think NAFTA was a Republican dream come true, and many Democrats were complicit!!!!
