Betting market odds for SCOTUS letting Trump keep his tariffs have tanked
A good day to re-up this thread on why tariffs are a poor tax policy instrument.
Also relevant today, this broad use of tariffs definitely exceeds the President's authority under IEEPA.
Early indications suggest the court agrees.

At least these small businesses are standing up for the integrity of the constitution (and demonstrating the harmful economic effects of tariffs).

A district court would preliminarily enjoin the razing but SCOTUS would stay the PI and allow the razing to occur while litigation concerning the razing’s legality proceeds.
As a matter of current law, could the president just…knock down the entire White House? Just raze the whole thing to the ground?

Trump’s tariffs as fiscal folly
In 2025, the US government underwent a large fiscal switch, with Congress enacting large income tax cuts and the second Trump administration putting new tariffs on goods at levels not seen in the US since the Great Depression. This column evaluates tariffs as a broad tool of fiscal policy, reviewing both tax policy and macroeconomic considerations, and concludes that this fiscal switch will leave most Americans worse off.

Ok so the Trump administration blew up the international agreement to tax CO2 from shipping. 14 years ago the Obama administration successfully opposed applying the EU carbon price to US airlines operating in Europe.
Just because Ds and Rs both agree on something doesn't mean it's right.
