From The Atlantic, How American Politics Went Insane by Jonathan Rauch
The informal constitution’s intermediaries have many names and faces: state and national party committees, county party chairs, congressional subcommittees, leadership pacs, convention delegates, bundlers, and countless more. For purposes of this essay, I’ll call them all middlemen, because all of them mediated between disorganized swarms of politicians and disorganized swarms of voters, thereby performing the indispensable task that the great political scientist James Q. Wilson called “assembling power in the formal government.”
The middlemen could be undemocratic, high-handed, devious, secretive. But they had one great virtue: They brought order from chaos. They encouraged coordination, interdependency, and mutual accountability. They discouraged solipsistic and antisocial political behavior. A loyal, time-serving member of Congress could expect easy renomination, financial help, promotion through the ranks of committees and leadership jobs, and a new airport or research center for his district. A turncoat or troublemaker, by contrast, could expect to encounter ostracism, marginalization, and difficulties with fund-raising. The system was hierarchical, but it was not authoritarian. Even the lowliest precinct walker or officeholder had a role and a voice and could expect a reward for loyalty; even the highest party boss had to cater to multiple constituencies and fend off periodic challengers.
