This issue has been on the front burner for quite some time and it is looking less likely that the USMC will be ratified by years end, with congress obsessed with impeachment hearings and the incoming IG report. Pelosi’s as being the speaker of the house has never intended to sign the USMC formally known as NAFTA into law due to the fact Democrats don’t want to give Trump any victories, and that most from the Big Club who are bought and owned by the COC, China, that is dictating economic policy of Wall Street and the Multi-national interests are opposed to its ratification as well.
Excerpt from linked article is the main thesis:
"The U.S. multinationals on Wall Street do not want the USMCA to pass because they don’t want President Trump to have leverage that allows him to continue the fight against China and the EU. It is a simple dynamic, USMCA ratification makes the Wall Street prior investments in China worth less.
In all of these efforts U.S. multinational corporations, big companies on Wall St, are heavily opposed to President Trump because they have invested in those overseas operations. Those companies facilitated the loss of U.S. manufacturing jobs"
