Well, quite obviously - after the cabal had to kill JFK back in 1963 to keep their businesses going.

Ted was the final nail in the coffin after (most probably) killing his mistress.

And the latest puppet, the spineless JFK Jr. was just for herding the MAHA sheep into the Trump corall.

You can actually correlate the family clan’s meaningless path with the declining power and importance of the Catholic Church

Since the Kennedys have always been in bed with the US branch of the Italian Mafia - which itself has been (most probably) founded but certainly controlled since by the Vatican.

And the latter’s decline started with Vaticanum II (aftermath of 1965).

So, the Kennedy clan has long since fallen out of favor - and no one of ‘em will ever get back in power.
