Trump knows millions and millions and millions of American citizens voted more for Biden than him.
His game plan is not to find more votes for himself, but to throw out the constitutional right to vote for these millions and millions of citizens, to disenfranchise them of their obvious choice, to not give Trump a second term.
The full plan is to throw out the votes of the electors, we the people chose with our vote due to antics and hand WOVEN doubt perpetrated by him and his occultists, and have the house of representatives choose.
The house gets only 1 vote per state so the representatives for each state have to agree by majority, who they pick.
There are more republican state governors etc, than democratic. He thinks they will choose him over Biden, he thinks they will choose him, over the will of the citizen voters of their state... He thinks republican representatives of the states will vote to NOT REPRESENT the voters of that state.
Subvert democracy.
