no, not really - the thing is that Joe Bidens mental / cognitive dysfunction is caused by a disease known as Alzheimers
The Royal families daft behavior and amorphous, asymmetrical appearance is caused by generations of inbreeding.
Hate to say so but the Biden men are quite normal looking - even handsome looking. Jill Biden is quite "normal" as well and they aren't stupid so much as they are morally vapid.

Charles should abdicate in favor of William. His grand uncle did so in favor of his grandfather and that is why his mother became queen when George VI passed away. If his grand uncle was barred from ascending the throne based on his desire to marry Wallace Simpson, Charlie's marriage to Camile is the same.

Now that you've mentioned it, let's go Charlie?

Well now that's just plain creepy. Too eerily similar looking.
