Noam Scheiber in The New Republic:
When Democrats contemplate the apocalypse these days, they have visions of Barack Obama and Hillary Clinton slugging it out à la Ted Kennedy and Jimmy Carter at the 1980 convention. The campaign’s current trajectory is, in fact, alarmingly similar to the one that produced that disastrous affair. Back then, Carter had built up a delegate lead with early wins in Iowa, New Hampshire, and several Southern states. But, as the primary season dragged on, Kennedy began pocketing big states and gaining momentum. Once all the voting ended and Kennedy came up short, he eyed the New York convention as a kind of Hail Mary.
Any candidate trailing at the convention must employ divisive tactics, almost by definition. For example, much of the bitterness in 1980 arose from the floor votes Kennedy engineered to drive a wedge between Carter and his delegates. At one point, Kennedy forced a vote on whether each state’s delegation should be split equally between men and women. Carter counted many feminists among his delegates, but the campaign initially opposed the measure so as to deny Kennedy a victory. “You had women who were with Jimmy Carter who were crying on the floor,” recalls Joe Trippi, then a young Kennedy organizer.
The Kennedy strategy worked both too well and not well enough.
