First, primary elections are far different beasts than general elections. They’re more like formalized polls to provide data for parties to select their candidates. The DNC definitely favored Clinton, but since parties are not public entities, there’s no rules saying they can’t do that. Unlike primary elections, the mechanics of the general election are laid out in the Constitution. Cheating in the general election is a far different proposition compared with conspiring with party officials to receive preferential treatment. One is a legal matter, the other is an intra-party matter.
Second, you’re understanding of the electoral college is either flawed or you’re being highly disingenuous. You can’t call the electors that voted for Trump “representatives of the state” any more than you can say that Clinton’s electors aren’t also representatives of the state. We, the people, vote to elect a slate of electors and if Trump’s fraud resulted in an incorrect slate of electors representing a state, the state’s vote was compromised and that can be remedied without infringing on those state’s rights.
But even that is irrelevant in this hypothetical situation. Clinton’s total of electoral votes could remain unchanged, and Trump would be ruled ineligible. All those state’s votes wouldn’t have to be changed, they just wouldn’t count in the same way that they wouldn’t count if they had voted for someone who was ineligible for some other reason (age requirement, place of birth, etc). That would leave Clinton as the candidate with the most electoral votes, 232, with no other eligible candidate having received any.
Please don’t take this as an endorsement of Clinton. I think she would have made a terrible President, though probably not as bad as Trump has been. I also find it highly unlikely that any evidence will ever come to light that makes Lessig’s hypothetical situation a reality. My interest in this subject is purely from a standpoint of American civics and, like it or not, there are “what if?” questions that, if proven, would make Clinton the President. As a Trump supporter, you shouldn’t let your hatred of Clinton blind you to the simple logic of what would happen in a hypothetical situation that’s highly unlikely to ever occur.
