While Trump argues the polls undersell his support, some Democrats say surveys showing Biden well ahead of the Democratic field are not to be trusted.
Both sides think a close race in 2020 is likely and that surveys showing Biden and other Democrats with huge leads aren’t likely to reflect Election Day’s reality.
“Anyone who believes that the Democratic candidate is headed for a landslide victory right now is doomed to repeat the tragic history of 2016,” Kofinis said. “It’s a fundamental mistake for anyone to believe that reality can be projected or predicted based on these polls this far out from the general election.”
The doubts surrounding polls underscore the degree to which confidence in the polling industry collapsed in 2016, when much of the public was blindsided by Trump’s victory.
