HHH will most certainly enter the race- no way in hell is LBJ letting RFK be acclaimed as the Democratic nominee. Another POD is LBJ announcing his retirement in the SOTU as was originally planned, which gives everyone more time and RFK the chance to enter all the primaries. HHH would not enter the primaries except via favorite-son proxies. I don't have access to the '68 Newsweeks anymore, but they make clear that this was the Humphrey camp's strategy.
