This sentence is Constitutional science fiction.
The “election” that Trump "won" has no Constitutional existence. The 50 State Legislatures which appoint 535 Electors (and Congress, which appoints 3) have all adopted the custom of having people voting as the means by which the appointments are normally made, but this creates 51 elections, not one.
Those 51 elections occur at the direction of, and are subservient to, 50 legislatures and Congress. The States unwisely granted Congress 3 Electors by ratifying the XXIII Amendment in 1960, so Congress does have supervisory power OVER THOSE THREE, but not otherwise.
There is only one Presidential election in the Constitution, it takes place in December, there are 538 voters, and in December 2020 Biden got 306 of them and was elected President.
No State Legislature objected that its Electors were not the ones they had appointed. No State Legislature even convened to consider the matter. In the case of Pennsylvania, the Legislature fled to avoid considering the matter.
It has never been alleged that a single one of the 306 votes for Biden/Harris was a forgery, that the Electors who casted them were impersonating someone else, or that the Legislatures had secretly appointed other Electors.
There is zero space for an allegation of fraud in the Constitutional Presidential election of December 14, 2020.
As far as the 51 elections which occurred on November 3, 2020, they may very well have been rife with fraud, but since the appointment power of the 50 State Legislatures (535) and Congress (3) is plenary, that’s a problem for those legislatures to deal with should they choose to do so.
If the US does not hold elections in November, how are electors chosen, what basis, for the actual presidential election in congress in December?
If that is considered a valid statement, then the corollary is that we have a constitutional system that guarantees a Democrat President for as long as this country continues to exist.
Because while the Electoral College vote that elected the President was unquestionably valid, the State elections which selected the Electors were rife with fraud. Democrat fraud.
Democrat-controlled States have enough Electoral votes to insure the outcome of the Electoral College vote in perpetuity. Six Democrat-controlled cities determine the results. The governments in those cities are not legitimately elected by votes of their residents. But when Democrats count the votes, Democrats always win the "elections".
Voters do not matter at all. Only the people who count the ballots matter. And those people make the counts add up to whatever their masters wish them to be.
The rulers "elected" by that system are self-destructive, but they are willing to destroy the rest of us before they fall.
It is not a system that can or should continue.
You forgot the most important part.
