Me neither. I can't imagine how a thing like that would be enforced. And it isn't all that different than the Republican legislatures that have passed laws to ensure that they don't need to accept election results they don't like. I wish it didn't ring of a certain hypocrisy to believe in this kind of double standard. But given the stakes, I can't help feeling that way.
What's certain is that it's a terrible place to be as a country when neither party really believes in the legitimacy of their opponents' votes.
