Despite these immense challenges, America’s democratic process survived. Election administrators, poll workers and voters themselves rallied to deliver the highest voter turnout since women’s suffrage and the passage of the Voting Rights Act, with Democrats Joe Biden and Kamala Harris narrowly defeating Donald Trump and Mike Pence in an election that was closer than many analysts expected.
