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.”
