It has been said, less politely, that the difference between a Republican and a Democrat for a president is the difference between the meager choice of a red or a blue condom in prison. As for who will build the roads, libertarians have given up telling them that the free market will. Socialists have given up saying that some rotating union will. Anarchists have given up telling them that whoever wants to build them will do it themselves.
Practical questions, silly and as indicative of the state as they are, have been replaced with questions which presuppose the state without even the phantom of an alternative.
