New York Times: “By overwhelming margins, voters in Pennsylvania and Florida were repelled by President Trump’s conduct in the first general election debate, according to New York Times/Siena College surveys, as Joseph R. Biden Jr. maintained a lead in the two largest battleground states. Over all, Mr. Biden led by seven percentage points, 49 percent to 42 percent, among likely voters in Pennsylvania. He led by a similar margin, 47-42, among likely voters in Florida.”
“The surveys began Wednesday, before the early Friday announcement that President Trump had contracted the coronavirus. There was modest evidence of a shift in favor of Mr. Biden in interviews on Friday, including in Arizona where a Times/Siena survey is in progress, after controlling for the demographic and political characteristics of the respondents. One day of interviews is not enough to evaluate the consequences of a major political development, and it may be several days or longer before even the initial effects of Mr. Trump’s diagnosis can be ascertained by pollsters.”
