I mean, like what’s the point of coming to this country if you don’t even try to bore everybody with stories about your ethnic roots all the time? That’s totally un-American misbehavior, if you ask me. But German-Americans are that way. They’re different. They’re kind of like German-Germans, if you know what I’m saying. They’re tricky.

German-Americans are America’s largest single ethnic group (if you divide Hispanics into Mexican-Americans, Cuban-Americans, etc). In 2013, according to the Census bureau, 46m Americans claimed German ancestry: more than the number who traced their roots to Ireland (33m) or England (25m). In whole swathes of the northern United States, German-Americans outnumber any other group (see map). Some 41% of the people in Wisconsin are of Teutonic stock.

Yet despite their numbers, they are barely visible. Everyone knows that Michael Dukakis is Greek-American, the Kennedy clan hail from Ireland and Mario Cuomo was an Italian-American. Fewer notice that John Boehner, the Speaker of the House of Representatives, and Rand Paul, a senator from Kentucky with presidential ambitions, are of German origin.
