CNN published this, so I assume they must think it's plausible.
I figured it would say things like, "It could force the transfer of Social Security and Medicare to the states, as there is no obvious Constitutional warrant for the Federal government to run things like that." Or "Great Society Programs." Or "the EPA, already under threat from the Trump administration."
What it says instead is that originalism is about taking rights away from minority groups. That's either a complete misunderstanding of what the philosophy is about, or else it's a willful slander of the first order. The rights of minority groups are protected by explicit Constitutional language. Insisting on the original understanding of, say, the 14th Amendment is a way of preventing rights from getting watered down.
So too with originalism pointed toward the Bill of Rights. The way that rights get washed away is very often by sliding words into new meanings. Originalism is a stronghold against that move: it insists that, if you want to strip away the right, you have to actually go through the Article V process. Nothing else but that process will do, ensuring that decisions to alter basic rights must enjoy very broad public support.
My guess is that the misunderstanding -- if it is that -- is created by the reality that the original Founders didn't trust everyone equally, especially with what we have come to call "voting rights." However, that misses the point: the Founders didn't consider voting to be a right in the same way that free exercise of religion or free speech was a right. They thought that citizenship was a kind of office. Like any office, it should be filled only by people who have shown they are qualified for it. That's why they imposed things like property tests, which demonstrated 'skin in the game' as well as a kind of practical economic independence. The last was important because they doubted that those who were wholly dependent on someone else could really reason independently of that interest, which meant that giving votes to servants (say) would really mean giving extra votes to the landlord.
Originalism does not threaten to restore that idea of citizenship, because the concept of voting rights was created through explicit Constitutional actions such as the ratification of the 15th Amendment. An originalist couldn't rule in favor of a return to the earlier conception of citizenship even if he or she thought it was a better idea, just because of their commitment to originalism.
This should be better understood. Originalism is the only mode of interpretation that should be supported in a candidate for the Supreme Court. Otherwise, the court exists not to apply the laws chosen by the People in accordance with the Constitution, but to make new laws and alter the Constitution. That is no proper role for the Supreme Court, not even when they vote unanimously.
