AFAIK, Henley is wacko-loony-La La Land-left on EVERYTHING; Frey may not be a right-winger, but he's a lot farther in that direction than Henley.
As far as Walsh, I always thought he was a wacked-out liberal: "Bases are loaded and Nixon's at bat...time to change the batter" (Rocky Mountain Way, live version). Maybe he's changed since then, I don't know.
