Around the country, Democratic elected officials who in the pandemic’s early phase shut down cities and states more aggressively than most Republicans did — and saw their popularity soar — are using a different playbook today. Despite the deadly wave fueled by the Omicron variant, Democratic officials are largely skipping mask mandates and are fighting to keep schools open, sometimes in opposition to health care workers and their traditional allies in teachers’ unions.

The shift reflects a potential change in the nature of the threat now that millions of Americans are vaccinated and Omicron appears to be causing less serious disease. But it is also a political pivot. Democrats are keenly aware that Americans — including even some of the party’s loyal liberal voters — have changed their attitudes about the virus and that it could be perilous to let Republicans brand the Democrats the party of lockdowns and mandates.

“You’ll see more Democratic elected officials say that this is our forever now and we can’t live our lives sitting rocking in a corner,” said Brian Stryker, a partner at the polling firm ALG Research, whose work on Virginia’s elections last year indicated that school closures hurt Democrats. “We’ve just got to live with this virus.”
