You got that right but it goes a lot deeper. That's the critical problem with our entire governmental system underlying every political policy, congressional law, candidate qualification for office, and judicial decision. We have people in government positions, at all levels elected or not that swear to uphold the constitution but flagrantly do not! When was even just one removed from a position or an office, or impeached for not upholding their pledge???
Sure there are grey areas that may require scholarly debate and analysis to determine constitutionality of particular issues. But many policies, decisions, laws, etc., exist that are clear egregious affronts to the constitution.
If I had one suggestion/complaint I could make to our founding fathers, it would be that we have no quality control dept., i.e., a "constitutionality clearing house". It should not depend on which party is in power. "Activism" by definition is an affront to the constitution unless properly done thru the amendment process. But which it never is because it knowingly wouldn't succeed 99% of the time, and for good reason!
As it stands we are at the mercy of the initiative of politicians, (almost an oxymoron and certainly not a high point in the swamp of Washington), and if it happens, litigation on both sides is paid for by taxpayers. Or we're dependent on private citizens/organizations to fund extremely costly litigation, again taxpayers fund the government opposition. And even in that case, settlement decisions again fall prey to a mixed bag of originalist and activist attorneys general and judges! Folks, we're in a no win situation any way we look at it.
