There aren’t any openings on the Supreme Court, but that’s not stopping a major conservative group with ties to the billionaire Koch brothers from mobilizing for the next vacancy anyway.

Americans for Prosperity has hired a vice president of judicial strategy who will spearhead the organization’s push for confirmation of a strict constructionist — someone who interprets the Constitution narrowly, avoiding what conservatives see as judicial activistm — when the next opening arises. It’s part of a broader commitment from the influential Koch network to spend heavily on judicial engagement in 2018, and it’s the organization’s most significant move on the issue this year.
