I'm sure elimination is one option AB will consider. The same drink formula could be reintroduced under a different name and get someone like Billy Carter to endorse it.
A more likely outcome will be to buy, or rent, some recognized Republicans to do an intervention with the public . . . along the lines of Bud has apologized, they will never do it again, they give to the GOP, its our moral duty to forgive etc.
That alone would not return Bud to alcohol greatness but it would, perhaps, allow the brand to live on the periphery like a pardoned criminal.
I don't know that they will ever return to alcohol greatness. Maybe over the next generation, but it will be a while.
