"This wasn't the argument that I set out to make," that Congress must impeach President Trump, Yoni Appelbaum says at The Atlantic. But after researching the previous three impeachments in U.S. history, it became clear pundits and Democratic leaders "have overlearned the lessons of Bill Clinton's impeachment, which backfired on his accusers" in 1998, "and entirely forgotten the real significance of Andrew Johnson's" in 1868.

By Appelbaum's estimation, Trump's multi-pronged "attack on the very foundations of America's constitutional democracy" already more than qualifies him for impeachment and removal from office, but even if the Senate disagrees and fails to convict, the process is its own remedy "in five distinct forms," he explains in The Atlantic's March cover story, posted online late Wednesday:

In these five ways — shifting the public's attention to the president's debilities, tipping the balance of power away from him, skimming off the froth of conspiratorial thinking, moving the fight to a rule-bound forum, and dealing lasting damage to his political prospects — the impeachment process has succeeded in the past. In fact, it's the very efficacy of these past efforts that should give Congress pause; it's a process that should be triggered only when a president's betrayal of his basic duties requires it. But Trump's conduct clearly meets that threshold. The only question is whether Congress will act. [Yoni Appelbaum, The Atlantic]

"It is absurd to suggest that the Constitution would delineate a mechanism too potent to ever actually be employed," Appelbaum writes. "With a newly seated Democratic majority, the House of Representatives can no longer dodge its constitutional duty. It must immediately open a formal impeachment inquiry into President Trump, and bring the debate out of the court of public opinion and into Congress, where it belongs."
