I Alone Can Fix It: Donald J. Trump’s Catastrophic Final Year by Carol Leonnig and Philip Rucker:
On July 30, President Trump proposed delaying the election, such was his fear of losing. He did not have the power to do so, but nevertheless tweeted, “With Universal Mail-in Voting (not Absentee Voting, which is good), 2020 will be the most INACCURATE & FRAUDULENT Election in history. It will be a great embarrassment to the USA. Delay the Election until people can properly, securely and safely vote???”
The suggestion was laughable. The dates of presidential general elections are determined by the Congress, with power enshrined in Artlcle II of the Constitution. Since 1845, federal law has set the Tuesday after the first Monday of November as the date of the election. In 2020, that would be November 3. No president in history has ever successfully delayed an election, not even in times of war.
