I don't think Chin is losing.  The history of Muslim Bans shows Trump running away from challenges.  Chin, along with many others contesting the Muslim Bans, is being effective.  If Chin and the many others challenging the Muslim Bans weren't effective, we'd still be saddled with Muslim Ban I.  Their good work has relegated that misguided policy, along with Muslim Ban II, to the ash heap of history where it belongs.
