I'm torn on the originalism concept, I lean towards it as the intent but not necessarily a good way to function. Why I lean that way is because the constitution has a built-in clause on how to change it, if it was living and breathing then why would we have included the process to change it and make amendments?
I do find that so-called originalist members of the Senate that love the filibuster to be hypocritical considering it was a loophole and not an original part of the government. Of course that is a whole other can of worms.
