“IIRC, it was Bobby Kennedy who took LBJ out...until LBJ had him killed.”
I’m really hoping you were joking, but since it happened over 40 years ago, and since you really may not remember correctly, and there may be younger readers on the forum:
1. It was Eugene McCarthy who took LBJ out.
2. It was Sirhan Sirhan who killed Bobby Kennedy on the anniversary of the six-day war because of Kennedy’s support for Israel including a promise to replenish thier arsenal with 50 Phantom fighter jets if elected.
Not to be to picky here, but my recollection was that RFK's strong showing in the primaries was what led LBJ to not seek the nomination for president. It was LBJ who put his influence behind Humphrey who won the nomination and ran against Nixon in 1968. McCarthy lost the nomination after he cried at some event.
