“...beat them like a yard dog.”
Does he maybe mean a junkyard dog? This is reminiscent of his “rip-tootin’ “ description of the “country” barbecue he and Fat Albert threw at the White House, complete with jeans, Western shirts and designer loafers.
The quote should be memorialized, if for no other reason than to show what a phony, totally out of touch pretender he has always been
I think the saying he was trying to come up with was “beat ‘em like a rented mule”.
The other saying is “meaner than a junkyard dog”.
