Why not pass it, it is almost the same as NAFTA - very minor differences. It will not really help or hurt the economy. If you disagree, please point out the significant differences - be specific. I don't consider an increase from 62.5% USA, Mexcio, Canada content to be duty free to 75% content to be significant.
From "Global Edge" blog: "Overall, the shift from NAFTA to USCMA should not impact the three countries dramatically. Only certain industries will be affected, and only by a small amount. "
