John McLaughlin was an American pollster who worked for Donald Trump's 2016 election campaign. An Irish-American whose grandfather immigrated to the United States in 1876 and became an NYPD captain, he was born in Fort Dix, New Jersey while his father served in the "Fighting 69th" New York Infantry Regiment; his uncle was the regiment's colonel. In 2018, he spoke out against a Newsweek op-ed which criticized the prevalence of Irish-American conservative pundits in contrast to "sober" Protestant pundits during the 20th century, and he argued that the Irish-American vote swung several swing states towards the Republican Party due to the Democratic Party's identity politics.
