Senator Jim DeMint (R-SC) has announced that he will resign from the Senate to head the Heritage Foundation. There is some speculation that Governor Nikki Haley might fill the slot herself. As several other governors have done, she could resign from office and have her successor name her to the Senate -- a maneuver amounting to self-appointment. That move would be a big mistake. In 2009, Ken Rudin explained at NPR that voters resent self-appointment and governors usually lose when they try it. He offered the complete list of governors appointed to the Senate and the result of the succeeding election:
Montana, 1933 — Sen. Thomas Walsh (D) died. Gov. John Erickson (D) appointed self, lost 1934 primary.
