What Johnny Carson Could — and Couldn't — Do to Public Opinion
Every account of Johnny Carson's career eventually arrives at the same claim: that he could move public opinion just by deciding what to joke about. The 1973 toilet paper shortage he never actually reported, only joked about, is the story people reach for first. Tonight Show producer Peter LaSalle believed Carson could shift political opinion. Carson believed it too, at least some of the time. Until a 2021 study I co-authored, nobody had actually tested it.
I went back to it more fully for the book, comparing Gallup approval numbers for sitting presidents against Carson's own monologue and interview references to them, from 1972 through 1992. Nixon and Watergate are the clearest case, because the timeline is unusually well documented: Carson ramped up Watergate material in the fall of 1973 and winter of 1974, then eased off it in the spring and summer of 1974, right as impeachment and resignation started to look likely. He was reading the story, not driving it. He told Mike Wallace in 1979 that he did not keep firing at a target once it was already mortally wounded.
The Gallup trend backs that reading up. Nixon's approval moved with or without Carson's involvement, which argues against Carson as a singular driver of opinion. What he could do, and did do, was focus attention on a story after the news had already made it salient — amplification, not origination. The media critic John Leonard put it well in the Times in 1975: once Carson started making Watergate jokes, audiences understood it was now permissible to say the president was finished. That is real influence. It is also a much narrower kind than the folklore gives him credit for.
The last piece of the chapter asks a more current question: how does Carson himself read today, against the hosts who followed him? In an original survey, audiences still rate him ahead of Gutfeld, Fallon, Colbert and Kimmel on approachability, on experience, on confidence — decades after he left the desk. Whatever the format needed to work, viewers still recognize it when they see it. The book it belongs to is still in progress at LSU Press, but that finding alone has been worth the chapter.
