Sorry, I'm not Alfred, but here's one never elected:
"Edith Bolling Galt Wilson was second wife of the 28th President, Woodrow Wilson. She served as First Lady from 1915 to 1921. After the President suffered a severe stroke, she pre-screened all matters of state, functionally running the Executive branch of government for the remainder of Wilson's second term."
