'Unfathomably insane': Political pundits stunned by Biden's decision to step aside

Republicans and pundits Sunday reacted to President Joe Biden's decision to step aside as a Democratic candidate with shock and by calling for his resignation as president.

After Biden announced on X that he would "stand down" from his campaign, Republicans immediately said that he should also end his presidency.

"Breaking: Biden is Out! If Biden isn’t fit to run, he isn’t fit to be President," Donald Trump Jr. wrote. "Hundreds of millions of Americans & the world depends on POTUS being of sound mind & body! It’s no longer a joke & Democrats can’t keep pretending that he’s in charge. Enough of this nonsense!"

"If Joe Biden ends his reelection campaign, how can he justify remaining President?" Republican vice presidential nominee J.D. Vance asked.

Other pundits expressed shock at the decision.

"We’re living through one of the most unfathomably insane months in political history," Politico's Kyle Cheney noted.

"Selfless act. Country before ego. The Common Good," Luke Russert opined.

"The big lesson here? Bullying works," Olivia Nuzzi said.

"Father time is undefeated," Mark Cuban wrote.
