Robert Caro's Lessons on Political Power

In 1933, the New York State legislature approved an act to let a new public authority build two bridges. Nobody in Albany thought much of it. Buried in Section 9, though, was a single sentence allowing that authority to pay off its bonds by issuing new ones, for, in its words, "any other corporate purpose." That one clause was enough to turn a temporary bridge project into a machine for building almost anything in New York, for as long as its author wanted. The author was Robert Moses, and the machine he built from that sentence kept him the most powerful man in New York for thirty years, despite never winning a single election.

Moses and Lyndon Johnson never held the same office, built the same thing, or came from the same world, but both are the subjects of Robert Caro's biographies, which took him seven years to write about Moses and fifty years, across four volumes, to write about Johnson (00:00). Caro's work is less a history of two men than a field manual for how power is actually accumulated and used in American government. Put side by side, Moses and Johnson show two different routes to nearly the same destination: control that outlasts elections, outlasts bosses, and outlasts the laws meant to check it.

The Architecture of Permanence

Moses built more of New York's physical landscape than anyone before or since: the Triborough and Verrazzano bridges, the Cross Bronx Expressway, Jones Beach, Lincoln Center, Shea Stadium, two upstate power dams, and hundreds of parks and pools. Of the 899 miles of highway completed in New York State by 1964, Moses had built 672 of them, at a cost that would run into the hundreds of billions of dollars today (01:34). He did all this without ever being elected to anything. "You don't have to be elected," people told him for thirty years. His reply: "You don't have to be either" (01:57).

Part of the answer is that Moses wrote the laws that governed him. He was known as the best bill drafter in Albany, and he used that skill to grant himself powers that the legislators voting on his bills never noticed they were signing away (02:23). His main tool was the public authority, a government-created corporation that sells bonds to fund a single project, then is supposed to dissolve once the bonds are paid off. Moses's amendment to the 1933 Triborough Bridge Authority Act let the authority refinance its bonds indefinitely, and his added language let it build connecting roads and "facilities not inconsistent with the use of the project," which, read creatively, meant almost anything linked by road to a bridge (03:36, 04:26).

The money this unlocked was staggering. In 1946, New York City's entire government could legally borrow $150 million before hitting its debt limit. That same year, the Triborough Authority alone could borrow $360 million, more than double the city's own capacity (05:19). And because a bond is a contract, and the US Constitution bars states from passing laws that impair contracts, Moses could write his authority's powers directly into the bond covenants sold to investors. Once sold, those powers could not be revoked by any mayor, governor, or legislature, only by a full constitutional convention (05:47, 06:16).

None of this explains why Moses kept his jobs. Caro is clear that Moses was not personally corrupt:

"Robert Moses was not himself corrupt. He was, in fact, as uninterested in obtaining payoffs for himself as any public servant who ever lived." (07:36, Robert Caro)

So there were no charges to bring. Instead, Moses made himself impossible to fire by holding twelve government posts simultaneously, appointed by different mayors and governors, so no single official could remove him without also fighting the most popular man in New York (08:18). That popularity was earned honestly: he finished 1,700 park renovations in his first four months as parks commissioner, and because his agency had shovel-ready plans when the Depression hit, New York received one-seventh of all federal work relief money set aside for the entire country (10:03, 10:56). Mayors who disliked him had no alternative plans of their own. As Caro's account makes clear, a mayor "could either build the projects that Moses wanted to build or he could build nothing at all" (11:24).

Caro's larger argument is that Moses did not start out chasing power for its own sake. In the 1910s he was an idealistic reformer trying to replace Tammany Hall's patronage with honest government, and his reforms were crushed by the machine he opposed. He concluded that ideals without power are worthless. What followed, in Caro's telling, was a slow transformation:

"Power is not an instrument that its possessor can use with impunity. It is a drug that creates in the user a need for larger and larger doses, and Moses was a user." (14:31, Robert Caro)

The Senate's First Master

Lyndon Johnson's path ran the opposite direction. Caro finds little evidence of a coherent political ideology in Johnson's early career. When he arrived in the Senate, he saw that the Southern Dixiecrats held real power, and he reshaped himself to fit them. Caro once asked former Georgia senator Herman Talmadge whether young Senator Johnson had shown any sympathy for the condition of Black Americans. Talmadge's answer, recorded word for word by Caro, was blunt:

"He was with us in his heart. I believed him. I believed him." (15:48, Herman Talmadge, as recounted by Robert Caro)

Johnson later spearheaded the 1964 Civil Rights Act and the 1965 Voting Rights Act, the most significant civil rights laws since Reconstruction. Caro's point is not that Johnson was secretly principled all along. It is that Johnson sought power first and used it for ideals only once he actually had it.

Before the presidency and the vice presidency, Johnson was Senate majority leader, a job the founders had deliberately designed to have no real authority. When Johnson checked, the Library of Congress found the majority leader held exactly one formal power: the right to speak first on the floor. The job was so politically toxic that his two predecessors both lost their Senate seats trying to do it (16:43, 17:06). Johnson became leader at 44, in a chamber whose average age was around 60, largely because nobody else wanted the job (17:40). What he built from it was, in Caro's words, mastery of "an institution that had never before had a master" (16:43).

Johnson used three tactics. First, he made himself the source of every favor a senator might need: committee help, scheduling, a direct line to House Speaker Sam Rayburn, or campaign money from Texas oilmen (18:03, 18:24). He also seized control of committee assignments, shifting the system from pure seniority to a steering committee he controlled. When Tennessee senator Estes Kefauver crossed him in 1957, the coveted Foreign Relations seat Kefauver expected went instead to a junior senator named John F. Kennedy (18:47). Second, Johnson controlled the agenda by making unanimous consent agreements, which fix debate time and limit amendments, the norm before any bill could reach the floor. Illinois senator Paul Douglas summed up the effect: "Under Johnson, all the actions take place offstage before the play begins" (20:54). Third, Johnson made sure nearly all of the Senate's information passed through him, using committee staffers to track every senator's activity so he always knew what each one wanted and what he could trade for it (21:13).

The clearest demonstration is the Civil Rights Act of 1957. Johnson needed a bill that Northern liberals would accept and Southern Democrats would not filibuster, with the sticking point being whether Southern election officials accused of suppressing Black voters would face jury trials, which an all-white Southern jury would almost never convict (22:22, 22:42). Over seven months, Johnson assembled a deal that gave Western senators a federal dam project between Idaho and Oregon, gave Midwestern Republicans jury trial rights for striking union workers, and gave moderates a new right for Black citizens to serve on federal juries, while leaving the jury trial clause for Southern officials in place to keep Southern senators from blocking the bill (23:10, 23:30). None of those pieces had anything to do with voting rights. Only Johnson's private knowledge of what every senator wanted made the trade possible.

Read together, Moses and Johnson suggest that durable power rarely comes from a single dramatic seizure. It comes from identifying every lever already built into a system, a bond covenant, a committee seat, a procedural rule, and quietly making sure that lever runs through one person. Caro's biographies spend thousands of pages showing that this work is mostly unglamorous, legalistic, and easy to miss until, decades later, someone notices that one man has somehow become impossible to remove.
