because Nixon looked shifty. He was, of course, but that was a visual judgement, not about content.
Of course, the moment I go looking for an article about it, I find a paper saying that was due to sample bias. From 2017:
Debunking Nixon’s radio victory in the 1960 election: Re-analyzing the historical record and considering currently unexamined polling data
Highlights
•
The presumed Nixon victory among radio audiences is likely the product of Republican bias in the sample.
•
Newly considered polling data shows that Nixon’s gains on the radio were only with Republican listeners.
•
There is little evidence that television worked to the advantage of Kennedy and the disadvantage of Nixon.
•
The 1960 election should not be read as a triumph of style over substance.
Abstract
It is widely reported that Nixon won the first of the 1960 presidential debates among radio audiences while Kennedy carried television viewers, and further that Kennedy’s victory translated to an electoral victory. It is thus assumed that style trumped substance when politics entered the television age. However, the Nixon radio victory emerged in only a single poll conducted by Sindlinger and Company. Considering other polling data reveals Sindlinger’s finding is likely the result of a Republican bias in the sample and not a mass defection of Democrats swayed by Nixon’s substantive arguments. Voters found Kennedy ahead on substance as well as style. Considering the full historical context of the election, there is little evidence that television worked to the advantage of Kennedy and the disadvantage of Nixon, nor even much evidence that Kennedy was considered more attractive. We find no evidence that the first debate was decisive; we find it dubious that the debates overall produced a 2-million vote swing for Kennedy; we find it implausible that the first debate can be linked in any meaningful way to the outcome of the election. We find it more meaningful that Nixon turned a 5-to-3 Republican disadvantage into a razor-thin contest and that he largely did so using television during the final two weeks of the contest. The 1960 election should not be read as a triumph of style over substance. Correcting the misguided dismissal of substantive argument is crucial work scholars can contribute to the broader democratic project.
