Libertarians are the cheapest fucking buys of all time.
They will sell their souls to a man who would grind them into a paste and sell that paste as a protein snack to his cultists-- in exchange for a hollow, symbolic win that either impacts them in no way whatsoever or maliciously hurts people they don't like.
At least with other political groups you have to, you know, BRIBE them.
Libertarians are so used to receiving absolutely nothing that they will mistake the scent of a steak for a full meal.
That hollow, symbolic win could have been given to them by anyone other than Trump. If nobody else thinks a group's interests are worth listening to, don't be surprised when they start chasing after the tiniest morsels.
