'He’s gone too far': Analysts say Trump's antics are starting to turn tide of support

President Joe Biden's campaign has leaned into attacks on Donald Trump's authoritarian rhetoric — and there's some evidence that voters are beginning to notice.

The president has made protecting democracy a centerpiece of his re-election campaign as he faces a potential rematch against Trump, who has been hit with federal and state charges for trying to overturn his 2020 loss. Biden's team has highlighted recent remarks by the Republican frontrunner that historians say stinks of fascism, reported Politico.

“Every time he says it, we are going to call it out,” said Michael Tyler, the Biden campaign’s communications director. “He’s going to echo the rhetoric of Hitler and Mussolini, and we’re going to make sure that people understand just how serious that is every single time.”

Biden himself has called out Trump for comparing his political enemies to vermin and saying, "The blood of America is being poisoned" by immigrants, and while one campaign aide acknowledged that some voters may see comparisons between the former president and Adolf Hitler as over-the-top, pollsters are detecting new worries about the GOP favorite.

“We’re seeing in focus groups many more people comment that he’s too divisive, that ‘I don’t like his temperament,’ that ‘I don’t like his personality,’" said Celinda Lake, a pollster for Biden’s 2020 campaign. "It’s really starting to come back. He’s gone too far.”

Earlier this year, focus groups appeared less worried about Trump's authoritarian impulses, Lake said, and former Barack Obama campaign manager Jim Messina urged Biden to keep up the attacks.

"That this guy is even crazier than he used to be — and it takes a long time to get that through," Messina said. “I’m not worried about [voters] hearing about this stuff too much. I’m worried … if you don’t call him on it, that it becomes normative.”
