Answer Wiki. Ronald Reagan is the only U.S. president who has been divorced. One First Lady, Betty Ford, married and divorced before marrying a second husband, who became President Gerald Ford. Andrew Jackson's wife, Rachel, was divorced by her first husband, Lewis Robards, because she lived with Jackson while still married to Robards.
Hence an ex-president could (in theory) run for a seat in the House of Representatives, the Senate, or for any state office such as Governor. John Quincy Adams is the only former president to have served in the House of Representatives after his presidency. Andrew Johnson is the only former president to have served in the Senate after his presidency. Interestingly, it might be possible for a former President to run for the office of Vice President. This would seem strange, given that the Vice-President is expected to replace the President when necessary, and would thus seem to be in violation of the no more than two terms rule.
