GOP moved increasingly rightward, it turned its back on Holton. When Harry F. Byrd Jr. broke ranks with the increasingly liberal national Democrats and ran as an independent for the Senate in 1970, Holton insisted on running a Republican candidate rather than endorsing an independent. That eventually led to the nomination of Ray Garland. Byrd went on to win the three-way election with an absolute majority. Holton also encouraged a moderate Republican to run in the special election in 1971 to choose a successor for deceased Lieutenant Governor J. Sargeant Reynolds, an election that was won by another independent, populist Henry Howell. Holton was not eligible to run in 1973, as Virginia does not allow governors to serve consecutive terms. In 1973, Mills Godwin, the conservative former Democrat who had defeated Holton in the 1965 election, was the Republican nominee. Godwin had supported massive resistance to racial integration and had first identified himself as a Republican in his speech accepting the Virginia Republican convention's nomination for governor. Later life Following his term as governor, Holton served one year in the Nixon Administration as the Assistant Secretary of State for Congressional Relations. After leaving Washington, he practiced law as a shareholder at McCandlish Holton, P.C. Holton later unsuccessfully sought the Republican nomination for the United States Senate in 1978, finishing third in a race against Richard D. Obenshain, John Warner, and Nathan H. Miller. Warner subsequently became the nominee after Obenshain's death in a plane crash. Under Gov. Gerald Baliles (1987–91), he served as interim president of the Center for Innovative Technology in Northern Virginia, where he guided it through managerial difficulties. After his retirement, Holton supported moderate Republicans, including John Warner. As the Virginia Republican Party became more conservative, however, he found himself more in line with the state Democratic Party and endorsed several Democrats for statewide office, including his son-in-law, Governor Tim Kaine. Holton endorsed Barack Obama in the 2008 presidential election. The Holtons have four children: Tayloe, Anne, Woody, and Dwight. Anne is married to U.S. Senator and former Virginia Governor Tim Kaine, the nominee of the Democratic Party for Vice President of the United States in 2016. She was the first First Lady of Virginia to live in Virginia's Executive Mansion both as a child and as a First Lady. In January 2014, Anne Holton was named Virginia Secretary of Education.
