The Constitution specifies the date the Electors are counted. The second Wednesday after the first Monday in December IIRC. Further, the Constitution foresees a situation occurring such a state may not have selected their Electors or otherwise does not present their Electors to the College. No problem! The Electoral vote quorum is based on the votes actually cast, not the total possible. Example, California has their vote by mail tangled up in mismanagement, recounts or court actions thus could not submit them to the College for tally. Their Electoral votes cannot not be counted in the Electoral quorum count.
All Trump has to do is win 270 in solid red states to make it a moot point; or, even LESS if the Dems mess up blue states and they don't have the votes ready by the deadline.
If the Dems screw up both California and New York, Trump only has to win 226 EV to become President.
Not exactly. The Constitution lets Congress set the date that the Electors vote and submit their tallies to Congress.
Article II Section 1 Clause 3:
The Congress may determine the Time of chusing the Electors, and the Day on which they shall give their Votes; which Day shall be the same throughout the United States.
Clause 2 was superseded by the 12th amendment, but not clause 3.
