When the anecdote resurfaced during the 2019 presidential campaign, clips and quotes spread widely online as people debated and parodied the tale. The short bad dude line survived beyond the news cycle because it is self contained, instantly quotable and easy to reuse as a reaction in unrelated conversations.
