What Robert Caro learned about power after studying it for 50 years

Power, Persistence, and Access

• Robert Caro sees a limited resemblance between himself and his subjects, Lyndon Johnson and Robert Moses: a relentless refusal to accept “no,” and a determination to pursue every source and leave no stone unturned.
• His research depended on reaching people with unique information, even when they were reluctant to speak. He used documents to identify what a person could clarify, then asked specific questions that could lead to deeper explanations.
• Caro distinguishes his persistence from the ruthlessness of Johnson and Moses, whom he says were willing to do almost anything to achieve their aims.

Robert Moses: Idealism, Achievement, and Hardening

• Caro describes Moses’s early career as genuinely idealistic. Moses worked to reform civil-service hiring around merit and to give New Yorkers access to parks and beaches, including Jones Beach.
• Moses’s ability to build despite seemingly insurmountable obstacles illustrates political will and skill. Caro notes that barriers to construction existed even in Moses’s era, but Moses found ways around them.
• In Caro’s account, Moses changed. His drive to improve public life hardened into a conviction that projects should proceed regardless of opposition or human cost. Moses used people’s vulnerabilities against them and displaced thousands, including to build the Cross Bronx Expressway, which Caro calls a bad idea.
• Caro’s portrayal is not simply that everything Moses did was bad, or that the answer is to restore unchecked power. He sees a democratic dilemma: large projects can be blocked by competing interests, yet concentrated power can enable construction at the expense of public input and affected communities. Caro says societies sometimes need leaders capable of getting major things done, but he does not want another Moses operating without regard for consequences.
• Moses’s power rested partly on his popularity and partly on the interlocking authorities he accumulated. This made him difficult to remove for years. As his influence declined, Caro observed a poignant sign of his loss of power: people stopped calling his office to ask for favors.
• Caro doubts Moses recognized how much he had changed. If he could ask Moses one more question, he would ask whether Moses realized it himself.

Lyndon Johnson: Leverage, Persuasion, and Purpose

• Johnson’s persuasive manner worked in tandem with his institutional power. People knew he could help or obstruct their ambitions—for example, by influencing committee assignments or whether legislation passed. His personal force was backed by tangible leverage.
• Caro considers Johnson’s desire to change the country, particularly to improve life for poor people, a defining quality. He connects that purpose to Johnson’s experience teaching poor children in Cotulla, Texas.
• Caro credits Johnson with helping secure civil-rights and anti-poverty legislation that he believes would not otherwise have been achieved in the same way. He contrasts Johnson’s domestic ambitions with John F. Kennedy’s presidency, while acknowledging Kennedy’s strengths, especially in foreign policy.
• Johnson’s presidency ended in tragedy, in Caro’s view, because of Vietnam. Johnson’s escalation of the war remains a question Caro says he is still trying to understand.
• Caro also discusses the 1948 Texas Senate election. He sympathized with Coke Stevenson, whom he regarded as an idealist who could also govern effectively, and wished he had won. Stevenson, Caro says, did not anticipate the lengths Johnson would go to in order to win.

How Circumstances Enabled Large-Scale Work

• The Great Depression helped Moses build: large numbers of unemployed architects and workers were available, allowing him to hire them cheaply and demand intense work. Caro treats these economic conditions as an important part of Moses’s accomplishments, not merely background.
• Caro suggests that the prevalence of skilled, inexpensive labor also helps explain why older buildings could receive elaborate decoration, including stonework high on façades where few people would see it.

Caro’s Approach to Biography and Research

Caro describes several practices that guide his work:

• Decide what the book is about before writing. After learning from The Power Broker, he tries to articulate a book’s purpose in one sentence, or at most a paragraph.
• Think through the whole book, including its destination. He believes this helps prevent losing direction years into a long project.
• Build the account from extensive evidence. His research includes archives, documents, and interviews with people who experienced events firsthand.
• Pursue hard-to-reach sources. If a person is uniquely positioned to explain an event, Caro believes he must keep trying to reach them.
• Ask questions grounded in research. Documents can establish what happened; targeted questions can uncover how a decision was made and why particular people were treated differently.
• Expect the work to exceed what can be published. Caro’s original The Power Broker manuscript was about 1.05 million words; roughly 350,000 words had to be cut. He regrets that some valuable material never reached readers.
• Preserve unused research. Caro donated his papers to the New-York Historical Society, choosing accessibility in New York over higher offers elsewhere. His archive includes extensive interview notes and material on topics and figures he could not fully cover in his books.
• Use digital tools mainly to locate sources. Online resources can make finding documents and oral histories faster, but Caro says reading and evaluating the material remains the larger task.

Caro also points out that studying a prominent person can reveal the world around them. His research into Johnson led him to accounts of frontier settlement and the isolation of life in the Texas Hill Country. He emphasizes how loneliness and distance shaped the people who lived there, including Johnson’s family.

Solitude and Concentrated Work

Caro says working in isolation has affected both his work and personal life. He turns off his telephone and avoids interruptions during the day to protect his concentration, even though this can make it difficult to keep up with friends and calls.
