Which is more important to democracy:
(1) That politicians are able to foresee and predict every consequence of a legal principle they establish when they establish it, regardless of any advances in science and the other fruits of human reason long after they are dead; OR
(2) That legal principles be applied based on our most current and best understanding of facts, even though no one who represented The People in constructing that legal principle expected that result.
You cannot have both. One empowers elected officials over unelected officials, at the cost of binding our legal principles to outdated understandings of how the world works. The other ensures that our deepest principles continue to be applied to the best facts, at the cost of taking power away from the people and reposing it in an unelected bureaucracy. Both approaches will have some proportion of bad outcomes for both liberals and conservatives. In 2017, the proportions are that conservatives get more outcomes they like under originalist principles, so they mostly choose that one. Liberals get more outcomes they like under interpretations that read laws as setting up principles with evolving applications. But the mix depends on societal sentiment and the direction of social change. It could easily shift the other way.
Scalia et. al try to resolve this without biting the bullet. They contend that Congress will amend the Constitution to keep it up to date, so we can have the best of both worlds. But we can’t. That’s not actually how the real world works, as we’ve learned after experimented for a few hundred years. You really do have to choose between two imperfect options. They also contend that all other jurisprudence is boundless and just chooses outcomes it likes. This is also false. Both philosophies prohibit a judge from deciding a case based on the outcome they prefer. The historical inquiry involved in originalism is not objective science just like the social and scientific inquiry involved in other theories is not objective science. I do think it’s probably true that the jurisprudence preferred by most liberal justices has more room for intentionally or unintentionally injecting personal and political judgments into the process–but it’s not the kind of binary often set up by proponents of originalism.
There’s no clearly right choice. It’s a question of what you value more. I think a well-functioning democracy probably needs a powerful, elitist bureaucracy as a check on majority whims. But anyone who thinks it’s an easy call is not fully appreciating the downsides of each option.
