“Relatedly, a court may not set aside an agency’s policymaking decision solely because it might have been influenced by political considerations or prompted by an Administration’s priorities.”will make it VERY hard for the lower court to deny Commerce's explanation.

I'm not so sure. I think the Maryland challenge is based on Equal Protection because of the emails saying the question would help non-Hispanic whites.
The SC opinion only addresses the APA arguments.
