It might be that the very divisions Trump has stoked save him from being removed from office early.

It may also be that forces beyond his control now contribute to his ultimate and final undoing.

In the flurry of recriminations from Wednesday’s assault on the Capitol, the question has shifted from whether Trump would leave office to when and exactly how it all goes down. The president will almost certainly be impeached again by the House early this week, as official Washington realizes anew how bad last week was, and how bad things might get over the next nine days and beyond.

At stake are final judgments for history on Trump, including the possibility of disqualification from running for office again. The decisions ahead for lawmakers matter greatly for Trump and the future of the GOP, and also for internal Democratic politics and the agenda Biden hopes to enact.

The strongest argument Republicans are now offering against impeachment doesn’t try to defend Trump’s actions or even argue that he’s fit to stay in office through Jan. 20.

Instead, it’s an argument that the cause of national unity is best-served by waiting Trump out -- and hoping that no further political violence erupts in Washington, state capitals and even lawmakers’ homes.

Trump has barely cared about his legacy in any traditional sense, and this week’s White House attempts to remind people of his accomplishments aren’t likely to change things.

Last week left indelible marks on his permanent record. Actions in the coming days could not only influence how he’s remembered, but also how the country comes through a turbulent and troublesome period.
