Kicking a leg out from one of the pillars of our Republic isn't "so unimportant." Everytime some bozo trots out a new accusation on twitter it erodes confidence in our election system, irrespective of whether there's actual verifiable proof.
Mocking the clowns that are doing this is low hanging fruit, they deserve all the ridicule they are getting.
The truth is, this lie will be kept hanging on by liars and frauds just long enough to keep the knuckle dragging frothy mouthed red hat sycophants lathered up until the next election cycle. In other words no sane person believes this is going to change the prior election ("decertification" LOL), it's simply a tool meant to keep the imbeciles living in echo chambers mad.
