Exceptions That Prove The Rule (More Re: Rudy and Kerik)
Although I was correct to say that no mayor of New York City had gone on to higher office during the twentieth century (Ardolph Loges Kline, who served as mayor in 1913, also served from 1921 to 1923 in the House of Representatives, but election to the House surely represented a step down, not up), I was wrong to suggest that none had done so during the nineteenth century, either. DeWitt Clinton served as mayor of New York City off and on from 1803 to 1815, then served as governor of New York state from 1817 to 1823, while John Thompson Hoffman served as mayor from 1866 to 1868, then as governor from 1869 to 1873. (With thanks to several readers of this happy Corner who shared with me their detailed knowledge of the history New York.)
Rudy Giuliani may now cheer up. To become governor he won’t have to turn himself into the first mayor of New York City to achieve higher office in all of American history, only the first to do so in 135 years.
