As an aside, For all those who talk about corruption and getting money out of politics I suggest reading Federalist 10 by Madison. Its a deep analysis of a need for a republican democracy. Any government that depends on human virtuousness will fail. The only way to have a sustainable government is to have strong checks and balances and putting multiple factions with different interests against one another.
Remember, the authors of the constitution (large overlap) stated on the record that they expected they got a lot of it wrong, and expected large swathes of it to be amended and replaced once actual experience was obtained.
Yes, for those on one side of the spectrum the ruling orthodoxy is textual originalism. The founders themselves would have told the modern Supreme Court that it's bonkers.
