The first person we see in “Coastal Elites” — and for more than 20 minutes, the only person we see in “Coastal Elites” — is Miriam, a passionate retired teacher played by a flustered, silver-haired Bette Midler. Pleading across a table directly to the camera, which in this case represents a sympathetic cop, Miriam tells her side of the story that landed her in this interrogation room. Her furious bewilderment bleeds through every word — most especially any word relating to the president, a “him” whose name she dares not say even as she curses it. Miriam jokes that she’d fill in the religion question on the Census with “The New York Times” instead of “Jewish”; she hates Republicans almost as much as she loves her NPR tote bag. At this latter admission, she grins wide. “Don’t you do it, officer,” she faux-mocks. “Don’t you make fun of my tote bag!”
