Amelia Thomson-DeVeaux: “Support for impeachment had grown slowly over the course of 1974, but there still wasn’t an overwhelming public consensus behind it until right before Nixon left office in early August. And Republican support for Nixon had remained mostly strong, even in the face of a scandal that consumed his second term. As the truth about the scope of Nixon’s misconduct emerged, though, impeachment became increasingly popular and the president lost even his most fervent defenders in Congress.”

“Of course, there are many differences between the Nixon impeachment and the Democrats’ current inquiry, which is still in its early stages, and each impeachment investigation will unfold differently. But as today’s Republicans are scrutinized for signs that they might turn on Trump, it’s important to remember that even in Watergate, it took more than a year of investigation — and a lot of evidence against Nixon — to reach the point where Republicans like Hogan were voting for impeachment.”

Frank Rich: “For all the months of sensational revelations and criminal indictments (including of his campaign manager and former attorney general, John Mitchell), a Harris poll found that only 22 percent thought Nixon should leave office. Gallup put the president’s approval rating in the upper 30s, roughly where our current president stands now — lousy, but not apocalyptic. There had yet to be an impeachment resolution filed in Congress by even Nixon’s most partisan adversaries.”

“He had defied his political obituaries before, staging comebacks after a slush-fund scandal nearly cost him his vice-presidential perch on the GOP ticket in 1952 and again after his 1962 defeat in the California governor’s race prompted the angry ‘last press conference’ at which he vowed that ‘you won’t have Nixon to kick around anymore.’ Might Tricky Dick pull off another Houdini? He was capable of it, and, as it happened, it would take another full year of bombshells and firestorms after the televised Senate hearings before a clear majority of Americans (57 percent) finally told pollsters they wanted the president to go home. Only then did he oblige them, in August 1974.”

“Richard M. Nixon always denied it: to David Frost, to historians and to Lyndon B. Johnson, who had the strongest suspicions and the most cause for outrage at his successor’s rumored treachery. To them all, Nixon insisted that he had not sabotaged Johnson’s 1968 peace initiative to bring the war in Vietnam to an early conclusion. ‘My God. I would never do anything to encourage’ South Vietnam ‘not to come to the table,’ Nixon told Johnson, in a conversation captured on the White House taping system,” the New York Times reports.

“Now we know Nixon lied. A newfound cache of notes left by H. R. Haldeman, his closest aide, shows that Nixon directed his campaign’s efforts to scuttle the peace talks, which he feared could give his opponent, Vice President Hubert H. Humphrey, an edge in the 1968 election. On Oct. 22, 1968, he ordered Haldeman to ‘monkey wrench’ the initiative.”
