You know people can manage their stutter, right? And that it’s typically worse during childhood, and during old age, than it is during your 20s-50s? Biden has been on the record talking about his stutter for decades- there’s a 1994 interview with him about it. Before he had any reason to “make it up”. Republicans who don’t expect you to ever debunk their lies have to deny he has a stutter because they rely on playing the “stuttering = senile” card every chance they can.
