This is kind of funny in a few ways. Bagneris could have gone the other way with this endorsement but it wouldn't have been worth anything. The voters who pulled his lever in the primary were going to LaToya anyway. They were, first and foremost, an anti-Charbonnet vote and weren't really his to deliver. Here, on The Lens's map,we find the bulk of the Bagneris vote. (Shaded blue) It is situated in Lakeview and in the deepest, whitest, wealthiest Uptown precincts around Audubon Place and the Garden District.
Those are the voters and donors who locked in on Bagneris early when he went to Frank Stewart's house got all "both sidesey" about the monuments. Remember that?
Recall also that the anti-Desi "Not For Sale NOLA" PAC was funded by a cohort of reactionary "business leaders" dead set against what upper class white people in this town snidely refer to as a "machine." The Not For Sale group also donated heavily to Bagneris.
So really what we're looking at here are a block of white conservative voters with sympathies for old confederates who were looking at buying a primary candidate and will now buy a different one in the runoff. They are, themselves "not for sale" by anybody to anybody and they will be the first to tell you that. The Advocate decided to accompany the story about this transaction with a photo that featured a "Black Lives Matter" banner in the background. Somebody over there has a keen sense of irony.
