As effusive as President Donald Trump was about the significance of his NAFTA rewrite, he was cautious about its chances of getting through Congress next year. Polls suggest Democrats could retake the majority in the House of Representatives, and there is a significant number of Democrats voted against the original NAFTA, or who pledged to vote against the Trans-Pacific Partnership. The earliest a vote could come, because of timelines laid out in fast track, would be in February. But it's likely to be later, since that doesn't include the time needed for Congress to draft implementing legislation.
Canada and the U.S. reached a deal on NAFTA 2.0 late Sept. 30, which was announced a half hour before the deadline to release the text.
