Without Another Debate, the Campaign Became a Duel of TV Scenes

As the candidates raced to claim different corners of the national screen this week, it was “Undercover Boss” vs. “Roll the clip.”

In a typical election season — remember those? — right about now we would be preparing for, or recovering from, the final presidential debate. But Oct. 23, the date of a proposed CNN showdown that Kamala Harris accepted and Donald J. Trump declined, came and went without one.

Instead, as Ms. Harris and Mr. Trump raced to claim different corners of the national screen, they were essentially staging a virtual debate, presenting competing versions of themselves on strikingly different stages.

Mr. Trump substituted the debate podium with a takeout window, performing a shift on the fry cooker at a closed McDonald’s franchise and violating the occasional job protocol. It was a familiar kind of reality-TV stunt for a reality-TV candidate.

This time, however, he was not emulating “The Apprentice” but staging a political version of “Undercover Boss.”

On the CBS reality series, which aired 11 seasons from 2010 to 2022, company executives went incognito to work low-level jobs at their companies. The premise was to show bigwigs how the grunts lived. But it also served, in the years after the financial collapse and Great Recession, as a form of prime-time crisis P.R. Chief executives were people too, it told us; they shared common purpose and mutual respect with the rank and file.

Mr. Trump’s shift, which lasted less time than a single “Undercover Boss” episode, had different aims. Most overtly, it was a way of using virality — what news producer can resist footage of Donald Trump shoveling fries into a container? — to spread his unsubstantiated claim that Ms. Harris had lied about working at McDonald’s while in college. (As with his birtherism campaign against Barack Obama, media coverage generally noted that his charges were baseless, but the dust still got kicked up, the doubts potentially sown.)
