As reported two days ago on here, there were 19 Presidents who had served in the US House Of Representatives, almost 45 percent of all Presidents
When one examines state governors who became President, we discover that there were 17 such cases, two less than those who were Congressmen, so about 40 percent of all Presidents.
The list of state Governors who went to the White House include, in chronological order:
Martin Van Buren
James K. Polk
Rutherford B. Hayes
Franklin D. Roosevelt
George W. Bush
Four of these Presidents were NY Governor (Van Buren, Cleveland, TR, FDR), with three Virginia Governor (Jefferson, Monroe, Tyler), two from Ohio (Hayes, McKinley), and two from Tennessee (Polk and Johnson). There were also one each from New Jersey (Wilson), Massachusetts (Coolidge), Georgia (Carter), California (Reagan), Arkansas (Clinton), and Texas (George W. Bush).
Four ascended to the Presidency from the Vice Presidency, with John Tyler and Andrew Johnson not elected President later, while Theodore Roosevelt and Calvin Coolidge were elected President in their own right.
Five times in American history, we had one governor succeed another one–1845 when Polk succeeded Tyler; 1897 when McKinley succeeded Cleveland; 1901 when TR succeeded McKinley; 1981 when Reagan succeeded Carter; and 2001 when George W. Bush succeeded Clinton.
There were two periods of years when there were no governors in the White House–from Polk leaving office in 1849 until Andrew Johnson in 1865; and from FDR leaving office in 1945 until Carter in 1977.
Twenty eight of the last 40 years between 1977 and 2017 saw a total of four Governors in the Presidency, from Carter to Reagan to Clinton to George W. Bush.
