Any possible way for Pat Brown to get Democratic nominee in 1964 Presidential Election?

From what I'm looking at currently on Wikipedia is he had more popular votes than Lyndon Johnson, but he failed to win many contests.

So what way would it have been possible for him to win nominee?
 
Here are some ways:

1.) Nixon wins 1960, and thus Johnson doesn't have the advantage of incumbency. Kennedy doesn't run, while Wallace does. Thus the liberal vote is united and the southern bloc is fractured.

2.) Johnson declines to run for re-election and Bobby Kennedy doesn't feel obligated to carry on JFK's legacy.
 
Well, IOTL, he was just running as a surrogate for Johnson.

I suppose that if both JFK and LBJ were killed, a contested convention could draft Brown, although that's to me unlikely. Nixon winning in '60 is probably your best bet for this, I'd say.
