2020 Election Was Worst Polling Miss In 40 Years

Wall Street Journal: “Public opinion surveys ahead of the 2020 presidential election were the most inaccurate in 40 years, according to an expert panel convened by the main trade group for pollsters, which said its work hadn’t yet pointed to a way to correct the error.”

“In the aggregate, the panel said, polls overstated support for Democratic nominee Joe Biden by 3.9 percentage points in the national popular vote in the final two weeks of the campaign.”

“It was the most substantial error in polling since 1980, when surveys found it hard to measure the size of Ronald Reagan’s impending landslide and overstated support for President Jimmy Carter by 6 percentage points.”
