And for the sake of history, it’s worth noting that Barack Obama and Robert Kennedy aren’t exactly a good analogy in themselves. Obama is clearly the frontrunner, the presmptive nominee, and has an insurmountable delegate lead. Robert Kennedy was running 3rd in the delegate count going into California, and would have needed a concession and pact with Eugene McCarthy to overtake Vice President Hubert Humphrey for the nomination, something that would have been anything but a given. Many Kennedy delegates, for example, wouldn’t vote for McCarthy at the convention because of the hard feelings left over from the primary contests, effectively splitting the anti-war vote and letting Humphrey have the nomination.
