Jonathan Last: “For all the carping about polls, they’re usually correct. Even in the big surprise elections, like 2016, the polling was mostly accurate: Trump’s results were within the margin of error in almost every state.”
“But sometimes there are misses. It’s useful to look at the polling in Wisconsin to understand what happened last night because while the topline result is shocking, the numbers… aren’t really?”
“This isn’t the story of a polling miss so much as voter sentiment moving so fast that the polls were a few days behind it.”
