If the trial can’t be postponed so that Democrats can build a more methodical case (which might not matter anyway), the Democrats and the few Republicans they can peel away should switch gears and do a censure of Trump with some real teeth in it: they should pass very targeted legislation that would severely curb presidential power; as well as leave section 3 of the 14th Amendment as an open option if Trump starts to stir up trouble. As Trump gets bogged down with his legal and financial problems over the next months, he may no longer continue to look as attractive or powerful to his base or to the politicians who cling to it. Impeachment may not be necessary, as this strategy would solve the problem.

The War After the Election also recaps the findings of the Transition Integrity Project, a group that included former Congressmen, United States Senators, previous cabinet members, White House Chiefs of Staffs, Secretaries of Defense and Homeland Security and state governors whose “war games” in June 2020 predicted almost exactly what has been happening before and after the election which led to the January 6 attack on the Capitol and now beyond it.
