Furthermore (and I'm surprised the Denver Post didn't mention this), the decision was basically unanimous! Even the liberal justices agreed that Trump had the authority to impose 90% of the ban.  There was a dissent by three of the originalist/textualist justices (Thomas, Alito, Gorsuch), but their argument was that 100% of the travel ban should be allowed to stand.  So, the liberal/activist/"living constitutionalists" at the 9th Circuit (and lower the courts, I think in Hawaii and Washington) got slapped down ... again.
