Whenever anyone asks you for the political composition of the Ninth Circuit, here's something you can cite.
It's a left-leaning FLSA opinion. Ten judges disagree: "O’SCANNLAIN, Circuit Judge, with whom KOZINSKI,
GOULD, TALLMAN, BYBEE, CALLAHAN, BEA, M.
SMITH, IKUTA, N.R. SMITH, Circuit Judges, join,
dissenting from the denial of rehearing en banc:"
That's every judge appointed by a Republican president (except Judge Clifton) alongside Judges Gould and Tallman.
Ten judges, of course, is a fair piece removed from a majority of the 28 active judges currently on the Ninth Circuit.
