Johnson and several top officials, including Secretary of Defense Clark Clifford and Secretary of State Dean Rusk, struggled with what to do in a fascinating phone call on November 4, 1968, the day before the election.

Johnson speaks of not wanting to be “a McCarthy” and worries about the certainty that “we’ll be charged with trying to interfere with the election.”

Rusk also equivocates, telling Johnson that “I do not believe that any president can make any use of interceptions or telephone taps in any way that would involve politics. The moment we cross over that divide we are in a different kind of society. … We get a lot of information through these special channels that we don’t make public. For example, some of the malfeasances of senators and congressmen and other people. … I think that we must continue to respect the classification of that kind of material.”

Clifford chimes in with another concern: that Americans just couldn’t endure learning how the world actually works. “I think,” Clifford frets, “that some elements of the story are so shocking in their nature that I’m wondering whether it would be good for the country to disclose the story, and then possibly to have a certain individual elected. It could cast his whole administration under such doubts that I would think it would be inimical to our country’s interests.”
