For starters, whoever the mayor of L.A. is in 2028 (whether Karen Bass wins or runs for reelection), they would not have been as involved in the Olympic process as Anne Hidalgo has been. After Macron, she's the second in-line of being there from the very beginning when Paris announced that they were going to bid for the 2024 Olympics.
If anyone will get disgruntled over any L.A. Olympic criticism (aside from some board members here), it'll be the people who have been very close to this from day-one, like Casey Wasserman or if Eric Garcetti was still mayor (& who knows, even he might still have his two cents to say come the summer of 2028).
As far as Anne's F-bombs, looks like she just reached a breaking point (as everybody does) when they've been so involved in something so big for so long (just look at all the controversy that was here). She had a knee-jerk reaction to all of the anti-"wokisme" (lol still can't get over that) critics when all they did was just spin negative hyperbole & fake "outrage".
