FYI, they do not teach constitutional law in law school. The CALL it Constitutional Law, but it is not. It is a survey and ratification of all the unconstitutional “doctrines” the Leftist courts have made up over the years to give the feds sweeping and unlimited power.
Read Robert Bork’s, “The Tempting of America”.
My website, not yet done, also deals with this https://sonsofconstitutionalliberty.com/
I only browsed over the decision but it seemed that most of the cases they cited were in the past 15-20 years. The courts have been very busy making stuff up, continually expanding the purview of our unelected legislators aka judges!
What they teach in law school is that the collected opinions of Federal courts are Talmud to the Torah of the Constitution.
As such, they don’t CHANGE the Constitution - not exactly, anyway - but as they accumulate over time they alter irrevocably the way the document can be used to govern us.
