@Apollo 20 So who does get the nomination in 1972; Humphrey?
That's a damn good question. Scoop had the second largest bloc of delegate votes, Wallace was third. Of course, with Humphrey winning California, he'd pick up another 271. It's possible you wind up with a very messy multi-ballot affair that leaves nobody happy. The outcome ultimately depends on what the McGovern delegates do.
Delegate vote for presidential nomination (poached from Wikipedia)
George McGovern – 1,729 (57.37%)[15]
Henry M. Jackson – 525 (17.42%)
George Wallace – 382 (12.67%)
Shirley Chisholm – 152 (5.04%)
Terry Sanford – 78 (2.59%)
Hubert Humphrey – 67 (2.22%)
Wilbur Mills – 34 (1.13%)
Edmund Muskie – 25 (0.83%)
Ted Kennedy – 13 (0.43%)
Wayne Hays – 5 (0.17%)
Eugene McCarthy – 2 (0.07%)
Ramsey Clark – 1 (0.03%)
Walter Mondale – 1 (0.03%)
Who's the compromise there? Maybe Sanford? Mondale? Someone else not there? It's not obvious. Humphrey would have an uphill climb, and the hawkish Jackson seems a non-starter with the McGovern people who still control a strong plurality of the delegates. It's a fascinating question that could be a TL of its own.
