More likely explanation, given Gropey Joe's proclivities, could be that he tried to run his hand up a skirt not belonging to his wife Jill and the unwilling occupant of said skirt stomped on his foot. Don't know who this poor unfortunate could have been who may have ventured a little too close within Joe's grasp, but you know it couldn't possibly have been Kamala ... 'cuz her legs spread easier than warm butter, so there would have been no need to stomp on his foot. Maybe the woman (or a wretch who identifies as a woman ... oh, no! ... zzshart?!) whose skirt could have been violated could be one of his hapless campaign workers/care givers?
