Neither L.A. nor Paris has been implicated in any wrongdoing, so the host-city selection proceeded smoothly with the candidates giving brief presentations before the ratifying vote.
L.A.'s fait accompli presentation lasted 30 minutes with three videos and a series of eight speakers thanked each other, thanked the Olympic movement, thanked Paris and portrayed the self-congratulatory tone that has become the hallmark of some IOC meetings.
The delegation came to the stage wearing sneakers, which Wasserman talked about in his speech.
"Now, I know what you're thinking ... these LA guys seem pretty laid back," Wasserman said. " ... My grandfather told me the key to success was two simple things: Always be honest, and always stay true to who you are. Well, what you see onstage here today reflects who we are, and the unique brand of California-cool that we will bring to the 2028 Games."
Larry Probst, U.S. Olympic Committee chairman of the board, came the closest to any negative tone when he said: "It has been a formidable journey to get here, but we never gave up hope or confidence in our ability to support and advance the Olympic Movement."
It was two years ago that L.A.'s effort appeared to be over after the city lost to Boston in a competition to become the sole American bidder.
But when the Massachusetts capital withdrew over cost concerns, L.A. quickly stepped into what eventually became a two-city race with Paris for the 2024 Games.
The competition, which appeared to be close, took a dramatic turn with talk of the IOC naming two winners, giving 2024 to one city and 2028 to the other.
The move made sense because there have been so few candidate cities, so with two viable bids, Olympic leaders warmed to the idea of locking up summer hosts for the next 11 years.
The only question was: Which city would agree to take 2028?
