Amid all the revelations of corruption at the Supreme Court, one glib social media defense of the conservative justices has been about ideology. As the (ridiculous) argument goes, these scandals aren’t actually scandals because the gifts and cash that flowed from right-wing billionaires and conservative activist Leonard Leo’s dark money network don’t actually influence the justices. Why? Because the justices were already conservative and were always going to vote the way they voted on cases of interest to their paymasters.

But that analysis misses how corruption works on a systemic level.

As the Founders noted, judges are given lifetime appointments for the explicit purpose of preserving an “independent spirit” that allows them to change their views without fear of consequences. And in fact, data suggests that in the past, many conservative justices have become more liberal as they age.
