According to Leuchtenburg, each man "had one foot below the Mason-Dixon Line, one foot above." Roosevelt, a New Yorker, spent much of the last twenty-five years of his life in Warm Springs, Georgia, where he built a "Little White House." Truman, a Missourian, grew up in a pro-Confederate town but one that also looked West because of its history as the entrepôt for the Oregon Trail. Johnson, who hailed from the former Confederate state of Texas, was a westerner as much as a southerner.

Their intimate associations with the South gave these three presidents an empathy toward and acceptance in the region. In urging southerners to jettison outworn folkways, Roosevelt could speak as a neighbor and adopted son, Truman as a borderstater who had been taught to revere the Lost Cause, and Johnson as a native who had been scorned by Yankees. Leuchtenburg explores in fascinating detail how their unique attachment to "place" helped them to adopt shifting identities, which proved useful in healing rifts between North and South, in altering behavior in regard to race, and in fostering southern economic growth.

The White House Looks South is the monumental work of a master historian. At a time when race, class, and gender dominate historical writing, Leuchtenburg argues that place is no less significant. In a period when America is said to be homogenized, he shows that sectional distinctions persist. And in an era when political history is devalued, he demonstrates that government can profoundly affect people’s lives and that presidents can be change-makers.
