Democrat Joe Biden’s lead has expanded to double-digits against President Trump in the presidential election, an NPR/PBS NewsHour/Marist poll finds. Biden now leads Trump 53% to 42%, up from an 8-point advantage at the end of June.

It comes as 71% of Americans now see the coronavirus as a real threat, up significantly over the last several months, as more than 167,000 Americans have died and more than 5 million have become infected with the virus.

And yet, more than a third of Americans (35%) say they won’t get vaccinated when a vaccine comes available; 60% say they will. There are huge splits by education and party on this. Those with college degrees are 19 points more likely to get vaccinated than those without (72% to 53%), and Democrats are 23 points more likely than Republicans (71% to 48%).
