Donald Trump is running against Joe Biden. But he keeps bringing up another Democrat: Jimmy Carter

As Donald Trump campaigns for a return to the White House, he often reaches back more than 40 years and seven administrations to belittle President Joe Biden by comparing him to 99-year-old Jimmy Carter.

Most recently, Trump used his first campaign stop after the start of his criminal hush money trial in New York to needle the 46th president by saying the 39th president, a recently widowed hospice patient who left office in 1981, was selfishly pleased with Biden's record.

“Biden is the worst president in the history of our country, worse than Jimmy Carter by a long shot,” Trump said in a variation of a quip he has used throughout the 2024 campaign, including as former first lady Rosalynn Carter was on her deathbed. “Jimmy Carter is happy,” Trump continued about the two Democrats, “because he had a brilliant presidency compared to Biden.”


It was once common for Republicans like Trump to lampoon Carter. Many Democrats, including Presidents Bill Clinton and Barack Obama, kept their distance for years, too, after a roiled economy, energy shortages and an extended American hostage crisis led to Carter’s landslide defeat in 1980. The negative vibes waned, though, with the passage of time and reconsideration of Carter’s legacy as a political leader, Nobel laureate and global humanitarian.

That leaves some observers, Democrats especially, questioning Trump’s attempts to saddle Biden with the decades-old baggage of a frail man who closed his public life last November by silently leading the mourning for his wife of 77 years.
