No! Nancy does not become the temporary President!
20th amendment states terms for the President, VP, Congress, and Senate.
Nancy is up for re-election.
IF there is a delay, into 2021, Nancy must step down on Jan, 3 at noon, while waiting to be declared winner or BIG TIME LOSER!
The President has to step down Jan. 20th at Noon. That's 17 days difference
If you're going to cry out like 'Chicken Little', over something someone told you, at least fucking read the constitution!
