I think this dumb dynasty stuff is acceptable only because the only reason we know RFK Jr.'s name (vs. the other randos who throw their hat in the ring and get ignored) is because of the dynasty. If the media just treated him as a nobody who has no business running for president and clearly isn’t making a real bid to win, then they also wouldn’t treat his nobody relatives as having any legitimacy in political commentary, but since they do the former, they’ll also do the latter.
