Jimmy Carter’s life after the presidency set a bar that few others have followed | Jan-Werner Müller

Carter was a man of extraordinary integrity. No president after him succeeded at doing as much post-White House good

Jimmy Carter's presidency has been etched into historical memory as a failure. That judgment is curious, particularly when it comes from American conservatives; many of the right's favorite policies - deregulation and a ruthless fight against inflation, no matter the cost in unemployment - were actually started under Carter. Of course, the more that malaise can be associated with the peanut farmer from Georgia, the shinier becomes his successor, Ronald Reagan, conservatism's greatest 20th-century hero.

What should be beyond dispute is that Carter was the most successful ex-president of the postwar period, and perhaps the greatest former president, period. That has a lot do with his sheer integrity. But the fact that no former chief executive after Carter managed to emulate his model - using their skills and access to do genuinely important things in politics, rather than mostly cashing in - says much about our times.
