The Kennedys got off pretty easily, since nobody was either surprised or very upset.

It may be that the Johnson family started the downward descent, since some of the family shenanigans made a Quantrill raid look like a sorority social by comparison; but most of the (known) notorious stuff happened after Lyndon died and nobody really cared by then.

On the other hand, maybe nobody cared enough what the Johnson family did to even notice much of it then.

There were comments "way back when" that pointed out that the Kennedys cared enough to avoid notice, while the Johnsons flaunted their behavour and relied on suppressing notice - - - but that's a different subject for later, maybe.
