I read an article saying that basically everyone that watched the ad came away with much less support for Harris. It triggers the exact portion of people’s lizard brain that they use to make their political choices. It was the 2024 version of the “Willie Horton” ad.
The only fast food I enjoyed in recent memory was Pizza Hut. During some scare about MSG they removed all of the MSG and I ordered it a time or two after that and it was nearly inedible.
I suspect similar things happened with other types of fast food. I think there’s a flanderization effect happening with a lot of it. The same is definitively not the case for things like pizza in general, as I can order from my local NY-style pizza place and pizza is still just as good as it ever was.
All that is to say it wouldn’t surprise me at all if fast food was objectively shittier across a number of different metrics.
