Have you heard the one about Trump? Biden tries humor on the campaign trail

WASHINGTON (AP) — President Joe Biden is out to win votes by scoring some laughs at the expense of Donald Trump, unleashing mockery with the goal of getting under the former president's thin skin and reminding the country of his blunders.

The jokes are the latest attempt to crack the code on how to clap back at Trump, whose own insult comedy schtick has redrawn the boundaries of what is acceptable in modern politics. Few have had much luck, whether they try to take the high road or get down and dirty with Trump, the presumptive Republican nominee for president.

“This is a constant challenge,” said Eric Schultz, a senior adviser to former President Barack Obama. Trump is “not someone who plays by the rules. So it’s up to Biden to figure out how to adapt and play by new rules of engagement.”
