Only Congressman Mark Sanford (R-SC) seems willing to stand up to the President, even though there is rare unanimity among congressional Republicans that the President's tariffs are a bad idea. The tariffs are potentially an economically devastating issue. They will raise consumer prices, raise costs to businesses, and not actually keep American industries afloat. They will spark a trade war where it is the United States vs. the world.
Congressional Republicans could build a coalition with Democrats to quickly pass a measure blocking the President, or at least quickly reversing the President. They could pass Senator Mike Lee's Global Trade Accountability Act. They could even simply reconsider section 232 of the Trade Expansion Act, which is what the President is relying on to implement tariffs.
They could get Democrat support to ensure veto protection by sunsetting any action for January 2021 so Democrats do not feel like they might be binding a future Democratic president.
This is entirely doable. There is near unanimity among Republicans. There is a strong desire by congressmen for Congress to reassert itself in turf fights with the executive branch. This is the perfect storm.
But Republicans lack the balls to do anything. That's the plain, hard truth. Donald Trump is Ramsey Bolton and the congressional GOP are Theon Greyjoy.
