Data Drives Nearly Every Clinton Decision

Politico: “What cities Clinton campaigns in and what states she competes in, when she emails supporters and how those emails are crafted, what doors volunteers knock on and what phone numbers they dial, who gets Facebook ads and who gets printed mailers — all those and more have Kriegel’s coding fingerprints on them.”

“To understand Kriegel’s role is to understand how Clinton has run her campaign — precise and efficient, meticulous and effective, and, yes, at times more mathematical than inspirational. Top Clinton advisers say almost no major decision is made in Brooklyn without first consulting Kriegel. He was one of her first hires and is among her highest-paid, and yet he remains virtually unknown outside the cloistered community of political number-crunchers.”
