Unpopular Opinion:
Trump had multiple paths for Tariffs, but chose the one that would get the most questionable legal pathway to buy time in the court. After 1yr of court challenges and Tariffs in place the whole time.. he loses, then uses the easy path and uses laws already passed by Congress to implement the new Tariffs.
Then if there is another court challenge, that will be tied up in the courts for another YEAR, he wins that case...Tariffs never go away and remain in place the WHOLE TIME
