I sniped this out of an LA Times article in terms of Trumpidiot trying to cancel the elections
The Los Angeles Times’ Evan Halper takes up the unsettling question of what would and would not happen if the pandemic is still raging this fall and Trump decides it’s no time for an election. To make one thing clear, Trump cannot just cancel a constitutionally mandated general election:
Technically, says Halper, Congress could delay the election for a bit in the case of an emergency, but when the president and vice-president’s terms run out on January 20, 2021, they are out of office, period. And in that case, it seems, the next-in-the-line-of-succession official who is still in office would be empowered to occupy the Oval Office.
If, of course, there’s no general election in November, Trump and Pence aren’t the only elected officials out of a job, so crazy things could happen. While the Speaker of the House is third in the line of presidential succession, Nancy Pelosi is also up for reelection this year and so would face the same scenario as Trump and Pence if the election were to be canceled. The next in the line of succession who does not face voters in November is Chuck Grassley, the Senate’s president pro tempore. But then again, 23 Republican senators are up for reelection this year and would be on the sidelines as well, so we could have a Democratic Senate and perhaps a president pro tempore Pat Leahy (that position traditionally goes to the oldest senator of the majority party).
