At the 2016 Republican National Convention, reporters from The Daily Show took the implication of "Make America Great Again" that America was once great seriously and went on the street to ask people, "When was America great?"

Yesterday at the Senate Judiciary Committee hearing on Judge Ketanji Brown Jackson's nomination for the Supreme Court, Senator Cory Booker quoted Langston Hughes's poem, "Let America Be America Again", whose title is somewhat similar to Trump's slogan, but whose point is quite different: "O, let America be America again – / The land that never has been yet".
