There really is no time context placed for the MAGA mantra.
Trump is not the first politician to use it as a campaign slogan, so don’t think he is a genius. He just copied others.
Republican senator Alexander Wiley employed the phrase in a speech at the third session of the 76th Congress ahead of the 1940 presidential election: “America needs a leader who can coordinate labor, capital, and management; who can give the man of enterprise encouragement, who can give them the spirit which will beget vision. That will make America great again.”
Similar phrases were used by Barry Goldwater in 1964.
“Let’s make America great again” was famously used in Ronald Reagan’s 1980 presidential campaign.
The phrase “Make America Great Again” is considered a loaded phrase. It is a loaded phrase because it doesn’t just appeal to people who hear it as racist coded language, but also to those who have felt a loss of status as other groups have become more empowered.
To back this thought, during the 2016 electoral campaign, Hillary Clinton suggested that Trump’s version, used as a campaign rallying cry, was a message to white Southerners that Trump was promising to “give you an economy you had 50 years ago, and move you back up on the social totem pole and other people down.”
