Biden's win came as voter turnout rose 7% over 2016, resulting in a total of 66% of U.S. adult citizens casting a ballot in the 2020 election, the Washington, D.C.-headquartered center said. Biden's popular vote differential was also better than fellow Democrat Hillary Clinton's 2016 two-point advantage, according to the fact tank.

The projection was a further sign of the scale of Donald J. Trump’s victory. In his first successful White House run in 2016, he received fewer votes nationally than Hillary Clinton.
