Republicans will never accept any sort of power-sharing agreement under any circumstance. They know that the Electoral College is all that matters and how they largely benefit from it. Notice how irrelevant Trump's seven million vote loss from 2020 is to the "stolen election" discourse. They will never consider abolishing it until they are the ones are the wrong side of an electoral college-popular vote split.
If the Dem Deep State did control things and was capable of 7D Chess moves, they would execute a plan where millions of Dems nationwide were told to intentionally not vote, but not in states that matte. Thereby ensuring the Dem loses the popular vote, but wins the EC. And the plan would be so precise that any post-election data analysis wouldn't catch any oddities. (obviously telling a few million in CA and NY to stay home would achieve the same goal, but it needs to look real)
