The Heritage Foundation is a pretty unpleasant organization itself. They may have started out with good intents sixty years ago, but these days the Foundation is more or less hell bent on the idea of establishing a right-wing evangelical theocracy. There is no question in my mind that they look at Trump as a ‘useful idiot’ to establish their perfect white protestant society, with men in charge, women in the kitchen, and people of colour either gone or not allowed to (effectively) vote. As you say, Shadowz, Project 2025 is just their latest ‘manifesto’.
The Electoral College is a weird thing. The worst parts of it are the elements that allow the vote to be subverted by individual electors. The electors ‘pledge’ to vote according to the votes cast in their district, but in reality nothing stops them from voting according to their personal desires. So an elector can, at least in theory, decide that their district voted ‘wrong’ and choose a different President than the people selected.
