David Leonhardt/NYT via PoliticalWire: “In the U.S., partisanship is the biggest factor determining vaccination rates. If Democratic voters made up their own country, it would be one of the world’s most vaccinated, with more than 91 percent of adults having received at least one shot. Only about 60 percent of Republican adults have done so. This vaccination gap has created a huge gap in death rates, one that has grown sharply during the second half of the year.”
