Pence’s odds of becoming President are long but not prohibitive. Of his forty-seven predecessors, nine eventually assumed the Presidency, because of a death or a resignation. After Lyndon Johnson decided to join the ticket with John F. Kennedy, he calculated his odds of ascension to be approximately one in four, and is said to have told Clare Boothe Luce, “I’m a gambling man, darling, and this is the only chance I’ve got.” Johnson may have been a gambler, but not an honest one. He stacked the deck.
