If you wonder why people are buzzing about the presidential prospects of a 37-year-old mayor of a midsize Midwestern city, read Pete Buttigieg’s memoir, Shortest Way Home. Buttigieg may be the intellectually deepest and most thoughtful of the Democratic presidential crop, despite his age. A history and literature major at Harvard and Rhodes Scholar, his deep love of novels comes through as he eloquently traces his roots in South Bend, interest in government, enlistment in the Navy reserves and deployment to Afghanistan, ascent to the mayoralty and, on the eve of his re-election, decision to come out as a gay man. A refreshing voice and a talented Millennial worth watching as he contemplates a run for the White House.
