He was a one-term wonder, reviled and scorned, granted an ignominious early retirement by American voters in 1980.
Now, 12 years after the Iranian hostage crisis dragged him to historic lows in the polls, James Earl Carter has emerged as America's most popular ex-president and the Third World's favorite mediator.
The 67-year-old former president, who comes to Baltimore today to help renovate 10 ramshackle rowhouses in a "blitz-building" program for Sandtown Habitat for Humanity, has prevailed by refusing to change.
The man who wore a cardigan sweater, urged Americans to turn down their thermostats and warned of malaise is still telling people things they probably don't want to hear. In announcing an anti-poverty initiative in Atlanta last year, the born-again Christian castigated area houses of worship.
"I see the churches as basically a dormant element of self-gratification and security," he said. "We don't even know what goes on outside this plastic shell we build around ourselves."
It was vintage Jimmy Carter -- his earnest manner, his idealistic bent, his solemn moral tone and his emphasis on getting personally involved.
Mr. Carter flies around the globe half a dozen or more times a year monitoring elections and talking with heads of state. He spends the third week of every June with Habitat for Humanity International, helping build or rebuild housing for the homeless. (This year, he is working in Washington and Baltimore.)
But he still tries to make sure he is back in Plains, Ga., each week to teach his Sunday school class.
When he shows up at the work site in West Baltimore this morning, don't expect the Naval Academy graduate to expound on world hunger or the problems of emerging democracies. Friends expect him to put in about 5 1/2 hours of hammering and sawing.
"It's a work camp, and that's what he's there to do," said Nancy McCutchen, associate director of Habitat's Jimmy Carter Work Project.
Last June, Ms. McCutchen helped the former president build 10 homes and a 4,000-square-foot day-care center in Miami's impoverished Liberty City neighborhood, the site of riots during Mr. Carter's presidency.
"He really felt good about going back and rebuilding," she said.
If Mr. Carter is admired in this country, he is revered in some Third World nations for his advocacy of human rights. He seems to be the world's busiest, and most prominent, election referee and self-employed peacemaker.
In 1989, he managed to persuade both sides of Ethiopia's bloody civil war to begin negotiations. When Nicaragua's Sandinistas were booted out of power by voters in 1990, Mr. Carter smoothed the transition by bringing together Sandinista leader Daniel Ortega and the victor, Violeta Chamorro.
Before the Panamanian elections of 1989, Mr. Carter spent several hours with strongman Gen. Manuel Noriega in a fruitless effort to persuade him to agree publicly to abide by the results.
After the balloting, Mr. Carter accused General Noriega of election fraud. (The general later was arrested by invading U.S. troops and taken to Miami for trial. He has since been convicted of drug charges.)
Mr. Carter has poll-watched during elections in Haiti, the Dominican Republic and Zambia.
His return to public life may date to 1982, when he began teaching at Emory University. Today, the Emory campus includes the Carter Presidential Library and the Carter Presidential Center, the former president's private think tank and foundation.
The Carter Center sponsors various mediation efforts, and raises money for public health and agriculture efforts, including a push to eradicate the Guinea worm, and a program to help small farmers increase crop yields in Ghana, Zambia and the Sudan.
Habitat for Humanity, started by a Georgia millionaire, is probably Mr. Carter's favorite charity. Since 1984, when Mr. Carter and his wife, Rosalynn, helped rebuild tenement apartments on New York's Lower East Side, they and volunteers have built 150 housing units in the United States and Mexico.
Mr. Carter launched the Atlanta Project in September, an effort to persuade the city's political, business and religious leaders to do more to help the poor.
Mr. Carter never seems to slow down, even when relaxing. Ms. McCutchen said she has been fly-fishing with the Carters in Colorado, and the pace is unrelenting.
"They get up very early in the morning and don't quit until late in the evening," she said.
