Post-presidency (1977–2006)
The Nixon pardon controversy eventually subsided. Ford's successor, Jimmy Carter, opened his 1977 inaugural address by praising the outgoing president, saying, "For myself and for our Nation, I want to thank my predecessor for all he has done to heal our land."
After leaving the White House, the Fords moved to Denver, Colorado. Ford successfully invested in oil with Marvin Davis, which later provided an income for Ford's children.
He continued to make appearances at events of historical and ceremonial significance to the nation, such as presidential inaugurals and memorial services. In January 1977, he became the president of Eisenhower Fellowships in Philadelphia, then served as the chairman of its board of trustees from 1980 to 1986. Later in 1977, he reluctantly agreed to be interviewed by James M. Naughton, a New York Times journalist who was given the assignment to write the former president's advance obituary, an article that would be updated prior to its eventual publication. In 1979, Ford published his autobiography, A Time to Heal (Harper/Reader's Digest, 454 pages). A review in Foreign Affairs described it as, "Serene, unruffled, unpretentious, like the author. This is the shortest and most honest of recent presidential memoirs, but there are no surprises, no deep probings of motives or events. No more here than meets the eye."
During the term of office of his successor, Jimmy Carter, Ford received monthly briefs by President Carter's senior staff on international and domestic issues, and was always invited to lunch at the White House whenever he was in Washington, D.C. Their close friendship developed after Carter had left office, with the catalyst being their trip together to the funeral of Anwar el-Sadat in 1981. Until Ford's death, Carter and his wife, Rosalynn, visited the Fords' home frequently. Ford and Carter served as honorary co-chairs of the National Commission on Federal Election Reform in 2001 and of the Continuity of Government Commission in 2002.
Like Presidents Carter, George H. W. Bush, and Bill Clinton, Ford was an honorary co-chair of the Council for Excellence in Government, a group dedicated to excellence in government performance, which provides leadership training to top federal employees. He also devoted much time to his love of golf, often playing both privately and in public events with comedian Bob Hope, a longtime friend. In 1977, he shot a hole in one during a Pro-am held in conjunction with the Danny Thomas Memphis Classic at Colonial Country Club in Memphis, Tennessee.
In 1977, Ford established the Gerald R. Ford Institute of Public Policy at Albion College in Albion, Michigan, to give undergraduates training in public policy. In April 1981, he opened the Gerald R. Ford Library in Ann Arbor, Michigan, on the north campus of his alma mater, the University of Michigan, followed in September by the Gerald R. Ford Museum in Grand Rapids.
Ford considered a run for the Republican nomination in 1980, forgoing numerous opportunities to serve on corporate boards to keep his options open for a rematch with Carter. Ford attacked Carter's conduct of the SALT II negotiations and foreign policy in the Middle East and Africa. Many have argued that Ford also wanted to exorcise his image as an "accidental president" and to win a term in his own right. Ford also believed the more conservative Ronald Reagan would be unable to defeat Carter and would hand the incumbent a second term. Ford was encouraged by his former secretary of state, Henry Kissinger, as well as governors Jim Rhodes of Ohio and Bill Clements of Texas to enter the race. On March 15, 1980, Ford announced that he would forgo a run for the Republican nomination, vowing to support the eventual nominee.
After securing the Republican nomination in 1980, Ronald Reagan considered his former rival Ford as a potential vice-presidential running mate, but negotiations between the Reagan and Ford camps at the Republican National Convention were unsuccessful. Ford conditioned his acceptance on Reagan's agreement to an unprecedented "co-presidency", giving Ford the power to control key executive branch appointments (such as Kissinger as Secretary of State and Alan Greenspan as Treasury Secretary). After rejecting these terms, Reagan offered the vice-presidential nomination instead to George H. W. Bush. Ford did appear in a campaign commercial for the Reagan-Bush ticket, in which he declared that the country would be "better served by a Reagan presidency rather than a continuation of the weak and politically expedient policies of Jimmy Carter". On October 8, 1980, Ford said former President Nixon's involvement in the general election potentially could negatively impact the Reagan campaign: "I think it would have been much more helpful if Mr. Nixon had stayed in the background during this campaign. It would have been much more beneficial to Ronald Reagan."
On October 3, 1980, Ford cast blame on Carter for the latter's charges of ineffectiveness on the part of the Federal Reserve Board due to his appointing of most of its members: "President Carter, when the going gets tough, will do anything to save his own political skin. This latest action by the president is cowardly."
Following the attempted assassination of Ronald Reagan, Ford told reporters while appearing at a fundraiser for Thomas Kean that criminals who use firearms should get the death penalty in the event someone is injured with the weapon.
In September 1981, Ford advised Reagan against succumbing to Wall Street demands and follow his own agenda for the economic policies of the U.S. during an appearance on Good Morning America: "He shouldn't let the gurus of Wall Street decide what the economic future of this country is going to be. They are wrong in my opinion." During a news conference on October 20, 1981, Ford stated that stopping the Reagan administration's Saudi arms package could have a large negative impact to American relations in the Middle East.
On March 24, 1982, Ford offered an endorsement of Reagan's economic policies while also stating the possibility of Reagan being met with a stalemate by Congress if not willing to compromise while in Washington.
Ford founded the annual AEI World Forum in 1982, and joined the American Enterprise Institute as a distinguished fellow. He was also awarded an honorary doctorate at Central Connecticut State University on March 23, 1988.
During an August 1982 fundraising reception, Ford stated his opposition to a constitutional amendment requiring the U.S. to have a balanced budget, citing a need to elect "members of the House and Senate who will immediately when Congress convenes act more responsibly in fiscal matters." Ford was a participant in the 1982 midterm elections, traveling to Tennessee in October of that year to help Republican candidates.
In January 1984, a letter signed by Ford and Carter and urging world leaders to extend their failed effort to end world hunger was released and sent to Secretary-General of the United Nations Javier Pérez de Cuéllar.
In 1987, Ford testified before the Senate Judiciary Committee in favor of District of Columbia Circuit Court judge and former Solicitor General Robert Bork after Bork was nominated by President Reagan to be an Associate Justice of the United States Supreme Court. Bork's nomination was rejected by a vote of 58–42.
In 1987, Ford's Humor and the Presidency, a book of humorous political anecdotes, was published.
By 1988, Ford was a member of several corporate boards including Commercial Credit, Nova Pharmaceutical, the Pullman Company, Tesoro Petroleum, and Tiger International, Inc. Ford also became an honorary director of Citigroup, a position he held until his death.
In October 1990, Ford appeared in Gettysburg, Pennsylvania with Bob Hope to commemorate the centennial anniversary of the birth of former president Dwight D. Eisenhower, where the two unveiled a plaque with the signatures of each living former president.
In April 1991, Ford joined former presidents Richard Nixon, Ronald Reagan, and Jimmy Carter, in supporting the Brady Bill. Three years later, he wrote to the U.S. House of Representatives, along with Carter and Reagan, in support of the assault weapons ban.
At the 1992 Republican National Convention, Ford compared the election cycle to his 1976 loss to Carter and urged attention be paid to electing a Republican Congress: "If it's change you want on Nov. 3, my friends, the place to start is not at the White House but in the United States' Capitol. Congress, as every school child knows, has the power of the purse. For nearly 40 years, Democratic majorities have held to the time-tested New Deal formula, tax and tax, spend and spend, elect and elect." (The Republicans would later win both Houses of Congress at the 1994 mid-term elections.)
In April 1997, Ford joined President Bill Clinton, former president Bush, and Nancy Reagan in signing the "Summit Declaration of Commitment" in advocating for participation by private citizens in solving domestic issues within the United States.
On January 20, 1998, during an interview at his Palm Springs home, Ford said the Republican Party's nominee in the 2000 presidential election would lose if the party turned ultra-conservative in their ideals: "If we get way over on the hard right of the political spectrum, we will not elect a Republican President. I worry about the party going down this ultra-conservative line. We ought to learn from the Democrats: when they were running ultra-liberal candidates, they didn't win."
In the prelude to the impeachment of President Clinton, Ford conferred with former president Carter and the two agreed to not speak publicly on the controversy, a pact broken by Carter when answering a question from a student at Emory University.
In October 2001, Ford broke with conservative members of the Republican Party by stating that gay and lesbian couples "ought to be treated equally. Period." He became the highest-ranking Republican to embrace full equality for gays and lesbians, stating his belief that there should be a federal amendment outlawing anti-gay job discrimination and expressing his hope that the Republican Party would reach out to gay and lesbian voters. He also was a member of the Republican Unity Coalition, which The New York Times described as "a group of prominent Republicans, including former President Gerald R. Ford, dedicated to making sexual orientation a non-issue in the Republican Party".
On November 22, 2004, New York Republican governor George Pataki named Ford and the other living former presidents (Carter, George H. W. Bush and Bill Clinton) as honorary members of the board rebuilding the World Trade Center.
In a pre-recorded embargoed interview with Bob Woodward of The Washington Post in July 2004, Ford stated that he disagreed "very strongly" with the Bush administration's choice of Iraq's alleged weapons of mass destruction as justification for its decision to invade Iraq, calling it a "big mistake" unrelated to the national security of the United States and indicating that he would not have gone to war had he been president. The details of the interview were not released until after Ford's death, as he requested.
