They didn't run a national campaign with Mulvaney in a swimsuit drinking Bud Light, they didn't put her on the cans, they didn't do anything but do a promotion on her channel.
I think its lazy to blame politics for a failed marketing campaign by creating some vilifying your own consumer base. We see the same pattern playing out in all aspects of products that have gone woke, games serving as the most recent example.
We live in a capitalist society and consumers will vote with their money and they cannot be forced to buy a product because the media and special interest groups decide to vilify and defame them publicly. This might work in a communist country but even then the effects are short lived.
Are you also aware the negative impact of putting images of someone that the customer base does not identify with or find beautiful influencing sales in a capitalist environment?
Have you got any proof of this? Everything I've read about it says it was just a single can sent for her to promote in a single video. Your argument hinges strongly on this claim, since a single can in a video is hard to square with "pushing woke ideology".
