Calvin Coolidge

30th President of the United States (1923–1929) — who cut taxes, reduced the national debt, and presided over the prosperity of the 1920s — known for extreme taciturnity ('Silent Cal') — whose hands-off governance is rehabilitated by conservatives as a model of constitutional restraint.

Creates the limited government constitutional presidency as a positive model — Coolidge's explicit belief that the President should not do too much (that congressional overreach was as dangerous as presidential overreach) represents the most coherent statement of constitutional conservatism at the presidential level.
