A study by Michigan State University researchers found that whether schools were open or remote in the fall of 2020 did not reflect the danger of COVID — but rather whether Democrats were in charge. As an example, they examined Michigan:

Michigan has more than 500 traditional public-school districts and nearly 300 charter school districts. Each school district had broad discretion on what to do that fall.

“As of August 2020, 59% of districts planned to provide at least the option of fully in-person education and 12% were fully remote only (others pursued hybrid strategies).”

The districts with the lowest share of Democratic voters had 72% in-person instruction. In districts with the highest share, only 41% offered in-person school.
