Across the country, the shutdowns have contributed to an exodus from public schools. In Fairfax County, for example, public school enrollment is down by more than 10,000 students since before the pandemic, a 5.5 percent decrease. Enrollment in New York City public schools declined by 4.5 percent, about 50,000 students. In California, public school enrollment decreased by 3 percent, or 160,000 students, the largest drop in 20 years. Because school budgets are partly dependent on head counts, these missing students could lead to severe cuts, making public schools even less attractive.

In an environment like this, Republican proposals to subsidize private school tuition are likely to be received gratefully by many parents. It’s a perilous situation for Democrats, the party of public schools. If they want to stanch the bleeding, they should treat the rollout of the children’s Covid vaccine as an opportunity to make public schools feel lively and joyful again.

Public schools may finally be open across the country, but in many districts, things are far from normal. In Fairfax County, an unvaccinated student identified as a “close contact” of someone who tests positive for Covid must quarantine for 14 days, no matter the results of the student’s own Covid tests. At some schools, students have been forbidden to talk during lunch. At my own kids’ school, students must be masked even during outdoor recess.
