Democrats do the exact same thing.
Biden swore 2020 elections were bulletproof when he won. Nothing has changed since then, but now he says 2024 will be illegitimate (meaning if they lose) and wants new voting laws despite nothing changing since he said there was no election fraud. So if the laws were fine why change them now?
Mr Biden casts doubt on election integrity as party rebels doom his voting overhaul agenda.

And democrats go beyond saying elections are wrong when they lose. In Virginia they had a white Democrat governor and they were happy, soon as a white Republican governor wins Democrats start saying it was a racist election.
Voters called ‘white supremacists’ elected a black Lt. Governor.

You can't blame Republicans for anything without being a hypocrite because democrats have done it also, and in a lot cases taken it further.
So if we can't even prove the election was false then why doesn't Biden need to prove it was rigged? Oh that's right because if he did prove it to validate his desire for new voting laws he would prove he cheated in the last election.
