The national mask mandate advocated by Joe Biden and others won’t save 130,000 lives by February because the vast majority of Americans already wear a mask in public, according to Phillip Magness in The Wall Street Journal.

Despite President Trump’s somewhat cavalier attitude toward face coverings, mask adoption to fight COVID-19 isn’t 49%, but north of 80%.
