In the spring of 2011, then-governor Mitch Daniels of Indiana announced he would not seek the Republican presidential nomination, ending months of excitement among conservatives around his possible run. His family’s reservations under the spotlight far outweighed any political pressure he may have been feeling, and he gracefully bowed out.

His decision was a low point for conservatives hungry for that Midwestern sensibility and sharp wit that Daniels embodied. The former political adviser to Ronald Reagan and head of George W. Bush’s Office of Management and Budget, Daniels was a rock star in the conservative movement. But the Daniels family had a complicated past. He and his wife had married, divorced, and eventually remarried one another.
