Clashing Over Jan. 6, Trump and Biden Show Reality Is at Stake in 2024

Rarely in American politics has a leading presidential candidate made such grave accusations about a rival: warning that he is willing to violate the Constitution. Claiming that he is eager to persecute political rivals. Calling him a dire threat to democracy.

Those arguments have come from President Biden’s speeches, including his forceful address on Friday, as he hammers away at his predecessor. But they are also now being brazenly wielded by Donald J. Trump, the only president to try to overthrow an American election.

Three years after the former president’s supporters stormed the Capitol, Mr. Trump and his campaign are engaged in an audacious attempt to paint Mr. Biden as the true menace to the nation’s foundational underpinnings. Mr. Trump’s strategy aims to upend a world in which he has publicly called for suspending the Constitution, vowed to turn political opponents into legal targets and suggested that the nation’s top military general should be executed.

The result has been a salvo of recriminations from the top candidates in each party, including competing events to mark Saturday’s third anniversary of the attack on the Capitol.

The eagerness from each man to paint the other as an imminent threat signals that their potential rematch this year will be framed as nothing short of a cataclysmic battle for the future of democracy — even as Mr. Trump tries to twist the very idea to suit his own ends.

“Donald Trump’s campaign is about him — not America, not you,” Mr. Biden said Friday, speaking near Valley Forge in Pennsylvania. “Donald Trump’s campaign is obsessed with the past, not the future. He’s willing to sacrifice our democracy, put himself in power.”
