Nice, sharp column by Jack Shafer.

Say what you will about Ralph Nader and H. Ross Perot, but they ran relatively honest campaigns on the issues, and the voters rejected them. The political market spoke many years ago and continues to speak: Telling the truth is not great for campaigns – and if it were, more people would be doing it.

The one presidential candidate in recent memory to win the White House posing as a truth teller was Jimmy Carter, who famously promised early in his campaign: “I’ll never tell a lie” and “I’ll never knowingly make a misstatement of fact” as president. These promises drew instant fire from the press, most notably Steven Brill, who flayed him in a March 1976 Harper’s piece titled “Jimmy Carter’s Pathetic Lies” (subscription required). Carter, who told no fewer lies than the average candidate, paid a political price for his promise, as everyone turned up their radar. “By saying that he would never tell a lie, Carter decided for himself that that’s going to be his standard,” said Alan Baron, George McGovern’s press secretary. “Well, fine, let’s hold him to it.” As soon as they could, voters replaced the non-lying liar with Ronald Reagan, a man so smooth even he didn’t know when he was lying.
