Brett Kavanaugh

Associate Justice of the United States Supreme Court (2018–) — former DC Circuit judge — Bush White House Staff Secretary — whose Senate confirmation was the most contentious since Bork (due to Christine Blasey Ford's sexual assault allegations) — a more centrist conservative voice than Alito or Thomas.

Creates the swing vote position on the current conservative supermajority — Kavanaugh's tendency to write narrowly and join majorities for smaller holdings rather than sweeping constitutional revisions makes him the de facto median justice on a court that formally has no swing justice.
