That’s certainly been my observation: visiting the uber-liberal cities of Portland ME and Portsmouth NH, I’m struck by the number of people wearing masks — not in stores, mind you, where everyone wears them regardless of politics just to avoid the harassment of panicked people, but everywhere.

Fascinating. I won’t bore you further, but if you’re curious about the phenomenon, Google “Democrats risk aversion” — it’s what they do, how they approach life.
