Doublespeak. Republicans actively work to twist the meaning of words to their base to fit their agenda, so that the other side playing by the rules and being fair looks like political cheating. That way Republicans can engage in political cheating themselves and claim self defense.
In today's flavor, "legal standard" means "the ability to make us lose" so they want to apply their own "legal standard" to democrats.
It sounds dumb to anyone paying attention, but their voters will eat this up.
Not the seat. The rim. The seat doesn't create a seal.
