evidence: Wearing masks is much more common among Democrats than Republicans. More than eight in 10 (81 percent) Democrats say they always wear a mask when leaving the house, while 55 percent of Republicans say the same. [...] There are larger partisan divisions about a national mask mandate than there are in mask usage. More than nine in 10 (93 percent) Democrats say they support passing a national mandate to require people wear a mask in public places to reduce the spread of COVID-19. Less than half (46 percent) of Republicans support such a policy. [...] Predictably, Democrats and Republicans differ sharply in their views. Seventy-two percent of Democrats completely disagree that wearing a mask is more about being politically correct, while 39 percent of Republicans say the same. Forty-five percent of Republicans somewhat or completely agree that wearing a mask is more about being politically correct than an important public health measure.
