In the summer of 1927, Coolidge vacationed in the [[Black Hills]] of [[South Dakota]]. While on vacation, he issued a terse statement that he would not seek a second full term as president: "[[I do not choose to run]] for President in 1928."{{sfn|Sobel|1998a|p=370}} After allowing the reporters to take that in, Coolidge elaborated. "If I take another term, I will be in the White House till 1933&nbsp;… Ten years in Washington is longer than any other man has had it—too long!"{{sfn|White|1938|p=361}} 

In his memoirs, Coolidge explained his decision not to run: "The Presidential office takes a heavy toll of those who occupy it and those who are dear to them. While we should not refuse to spend and be spent in the service of our country, it is hazardous to attempt what we feel is beyond our strength to accomplish."{{sfn|Coolidge|1929|p=239}} 

After leaving office, he and Grace returned to Northampton, where he wrote his memoirs. The Republicans retained the White House in 1928 when [[Herbert Hoover]] was elected in a landslide. Coolidge was reluctant to endorse Hoover. On one occasion he remarked, "for six years that man has given me unsolicited advice—all of it bad."{{sfn|Ferrell|1998|p=195}} But Coolidge had no desire to split the party by publicly opposing Hoover's nomination.{{sfn|Clemens|Daggett|1945|p={{page needed|date=June 2023}}}}
