President Biden showed up to vote in his hometown of Delaware early Monday and ended up standing in line behind a man wearing a vulgar pro-Donald Trump hat.

The red hat, which from a distance resembled Trump's classic Make America Great Again (MAGA) merch, upon closer inspection read: “Elect That Motherf—er Again!!”

Photos showed the 81-year-old Biden standing about nine spots behind the unidentified Trump supporter in line at the polling station in Wilmington.

The outgoing president, who remains commander in chief for less than three months, waited about 37 minutes to cast his vote.

Biden has had other unfortunate photo ops wearing pro-Trump hats – including briefly wearing one during a visit to Shanksville, Pennsylvania, on September 11th, which Republicans used to create memes on social media suggesting that he was with Harris is at the top of the Democratic ticket when he is dissatisfied with his forced resignation and his replacement by Vice President Kamala.

Biden came under pressure from his colleagues to end his re-election campaign after a dismal debate with Trump on June 27 that sparked a mutiny over the president's apparent cognitive decline.

Trump, 78, has claimed that the outgoing president was upset about the undignified end to his career.

Biden insisted to reporters on Monday that he has no regrets about abandoning his bid for a second term.

Asked by a reporter whether it was bittersweet to have voted for the 60-year-old Harris rather than himself, Biden replied: “That's sweet.”
