But he can be criticized for scaling back on agencies that handle pandemic preparedness, for downplaying it at almost every step, for making mask wearing or lack thereof a statement about which side you're on, for encouraging governors to open back up, for making the rules governing covid safety in churches a political fight, *takes a deep breath*, for questioning the death toll, for bleach comments, for promoting unproven drugs... am I missing things? Probably.
