“Let others wallow in Watergate, we are going to do our job,” said Richard Nixon with typical unearned self-righteousness in July 1973. By then, more than a year had passed since a slapstick posse of five had been caught in a bungled burglary at the Democratic National Committee headquarters in the Watergate complex. It had been nine months since Bob Woodward and Carl Bernstein reported in the Washington Post that the break-in was part of a “massive campaign of political spying and sabotage” conducted by all the president’s men against most of their political opponents. Now the nation was emerging from two solid months of Senate Watergate hearings, a riveting cavalcade of White House misfits and misdeeds viewed live by 71 percent of the public.

Even so, Nixon had some reason to hope that Americans would heed his admonition to change the channel. That summer, the Times reported that both Democratic and Republican congressmen back home for recess were finding “a certain numbness” about Watergate and no “public mandate for any action as bold as impeachment.”

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.
