MEXICO CITY — Vicente Fox, the former president of Mexico, was recently stuck in Mexico City traffic, overcome with frustration — not by the congestion, but by something that was irritating him even more:Donald J. Trump. He grabbed his phone, turned the lens on himself and pressed record.
“Ha! Donald,” Mr. Fox said, holding the phone perhaps a little too close to his face. “What about your apologies to Mexico, to Mexicans in the United States, to Mexicans in Mexico?”
In short order, the 15-second clip was on Mr. Fox’s Twitter feed — another salvo in a personal campaign against the American presidential candidate that has included television appearances, radio interviews and a fusillade of hectoring Twitter posts.
Mr. Fox’s voice is among a growing, if uncoordinated, chorus of influential Mexicans worried about what a Trump victory could mean for the complex relationship between the United States and Mexico — not to mention the impact Mr. Trump’s presidential bid may have already had.
The voices have included at least two former Mexican presidents, top government officials, political analysts, academics, editorial writers and cultural figures.
President Enrique Peña Nieto likened the candidate’s language to that of Hitler and Mussolini in an interview with Mexico’s Excelsior newspaper. And he recently shuffled his diplomatic corps in the United States, replacing Mexico’s ambassador to Washington and installing new consuls general around the country, in part to strengthen his administration’s response to the rise of Mr. Trump and what it reflects about American sentiment toward Mexico.
While many leaders around the world are worried about how Mr. Trump’s campaign, win or lose, could shape American foreign policy, the concerns are particularly pointed in Mexico and throughout the Mexican diaspora because of the exceptionally close geographic, economic, demographic and cultural ties between the two countries.
