The quotes of Justice Roberts are telling, and sound amazingly "Originalist". He even mentions "the Framers".
rn basically (if you don't care to read it) our government is too much, and un-Constitutionally, under the control of prosecutors. We all saw this with what happened between President Trump's first and now second term. He was jammed up in court with what he called "law-fare" (a riff on 'warfare'). Roberts basically argues that every future President could be similarly jammed up, just based on whether his successor liked him or not.
And that's just not what the Framers meant. Roberts says, "the preservation of our system of separated powers" is not supposed to be "up to the good faith of prosecutors".
If our "system of separated powers", which is framed in the Constitution, is going to be preserved by officers of the court somewhere, then that's going to be the Supreme Court. That's why the Originalist position in judicial philosophy is so important, and why Trump only nominates jurists approved by the Federalist Society, because that's what they care about, is interpreting the Constitution according to its original meaning.
