The electorate doesn't lose their rights when corrupt state legislatures or executive branch officials are derelict in their duties.
These states signed off on fraudulent elections and the rights of ALL voters were violated.
The legislatures of those states with corrupt executive branch officials should have just voted on their own slate of electors and sent them to Congress. They didn’t. Case closed.
And keep in mind that we are now in mid-2022, and nobody has yet been able to present sufficient evidence of election fraud in 2020 that would (1) hold up in a court of law, and (2) be sufficient to change the outcome of even a single state’s election results.
Voting for President and Vice President is not a US Constitutional right.
If all 50 State Legislatures appointed their Electors with no voting involved, the resulting President would be perfectly legally elected and entitled to the office.
