Sidney Stone Blumenthal (born November 6, 1948) is an American journalist and political operative. A former aide to President Bill Clinton, he is a long-time confidant of Hillary Clinton and was formerly employed by the Clinton Foundation. As a journalist, Blumenthal wrote about American politics and foreign policy. He is also the author of a multivolume biography of Abraham Lincoln, The Political Life of Abraham Lincoln. Three books of the planned five-volume series have already been published: A Self-Made Man, Wrestling With His Angel, and All the Powers of Earth. Subsequent volumes were planned for later. Blumenthal has written for publications such as The Washington Post, Vanity Fair, and The New Yorker, for whom he served for a time as the magazine's Washington correspondent, and, was, briefly, the Washington, D.C., bureau chief for Salon. He is a regular contributor to the openDemocracy website and was formerly a regular columnist for The Guardian. After 2000, he wrote several essays critical of the administration of George W. Bush.

Even as a writer at The Washington Post, where Blumenthal passed some time in the 1980s, he placed a porous membrane between his political views and his writing. It is the sort of partisan, if also intellectual, engagement that makes mainstream journalists, even those of liberal politics, deeply uncomfortable." Early life and career Blumenthal was born in Chicago, to interfaith family Claire (née Stone) and Hyman V. Blumenthal. His father was Jewish and mother Catholic. He became involved in politics at the age of 12 as a courier for a local Democratic party election precinct captain. Hearing John F. Kennedy reference The New York Times during a campaign rally Blumenthal attended prompted him to begin reading that paper regularly. He earned a BA in Sociology from Brandeis University in 1969.
