Donald Shelton Dawson (August 3, 1908 – December 25, 2005) was a 20th-century American lawyer, politician, and military officer, best remembered as the presidential aide who marshaled Harry S. Truman's crucial whistle-stop tour in the 1948 election campaign and so was perhaps the first modern American political advance man, able to gauge political climate and provide appropriate advice.
