The phrase comes from Joe Biden's May 2020 interview on The Breakfast Club with Charlamagne tha God, where he said voters torn between him and Donald Trump 'ain't black.' The remark drew immediate backlash, an apology later that day, and widespread coverage during the 2020 presidential campaign. Clips were remixed on social media and turned into a shorthand meme for blunt political gatekeeping. It remains in circulation because the short excerpt is instantly recognisable and easily reused in election discussions and parodies.
