The argument about the Electoral College is one about the process, not the mechanisms. By definition, the Electoral College is undemocratic in that for a choice of a national leader, people in smaller population states have a greater say than those in larger states.
You can argue that as the United States of America, that is a majority of the States that get to vote for the President, but not even the original writers of the Constitution thought that. The reason for the Electoral College was to put a break on the possibility of a populist being elected.
So the original purpose has proven to be unachieved, the argument that States should vote for the President instead of people is completely undemocratic.
And in this case the Republican claims of misnformation and conspiracy have seemed so outlandish and baseless it's hard to take any of them seriously.
Like videos of ballots being burned, that turned out to be sample ballots printed from the internet.
Or the false rumor that ballots marked with sharpie were being disqualified in Arizona when their own election officials repeatedly cleared that claim.
Or the baseless claim that Republican observers were not present for the counting of ballots in Michigan or Pennsylvania - they were.
Or the willful misunderstanding of how ballots were being tallied and reported.
Or that mail in ballots fraudulently skewed Democratic after Trump spent months telling his supporters not to trust mail voting, then complaining when those mailin ballots were legally counted after November 3rd.
NYT talked to every states election officials and not a single one could report large scale voting fraud, certainly not enough to affect this year's presidential election.
Would/Should Twitter put a little "this claim is disputed" banner on this tweet? If not, why not?
This has nothing to do with the factuality or legitimacy of flaws in the system -- in short, yes, I believe you that there are severe problems with the apparatus we use to conduct elections, but there is strong pressure to ignore and even deny these problems, because doing so helps solve the bigger, more important problem of getting Trump out of office. I don't want Trump in office, but I cannot admit to any legitimacy to the claims of vote irregularity in the 2020 election, even theoretically based on your expertise because even if it were true, it would be a "fact that gives power to the enemy" and thus must be treated as a falsehood. That's why if you post about it on Twitter, a little note will be attached to your tweet with a link that says the U.S. elections were perfectly conducted with no chance of fraud.
