Did you forget the civil war again IWRA?
Even then, when Lincoln was elected we had a peaceful transfer of power. The war came after Lincoln was inaugurated, and it wasn’t to install another president or prevent one from being installed.
Right.... so Jefferson Davis wasn't "another president" I see greyparrot beat me to it.
So we have some police being shoved vs large caliber mortars, but to you that's not precedent because Lincoln was sworn in. Okay...
I'm sure the Jan 6 crowd would have accepted Biden being sworn in as president of New York and California and nothing else if that helps clear things up.
Anyway though this isn't the first time there has been violent disagreement over the future of the federal government, it wasn't the first time people tried to cheat, it wouldn't have been the first time they ignored the electors (or choose electors based on their preference rather than the governors).
It is news worthy though because it's the first time in a long time people were angry enough to do something like this no matter what help they may have had from DOJ false flaggers.
