A year before the 2024 election, a divided nation is stuck in a political loop: President Trump’s weaknesses helped deliver President Biden to the White House, and now the incumbent’s vulnerabilities could lead his predecessor to a comeback.Biden, the nation’s oldest president at age 80, is poised to reclaim the party’s nomination, yet he has been dogged with questions about his age, frustration over his handling of the economy and anxiety about two wars. Trump, 77, has a comfortable lead as he seeks the Republican nomination for a third time, even as many moderate and independent voters are repelled by his repeated efforts to overturn the 2020 elections results and the many criminal indictments he faces.Copyright ©2023 Dow Jones & Company, Inc.
