Republican primary voters will face a big decision. Let’s hope they choose to move forward, not backward—in terms of repeating either discredited public policy or repeating sullied candidates.

Shaming the Republican base into blindly standing by a past president with such a checkered electoral record, no questions asked, is not going to cut it.

The question for Republicans is what will they do if—perhaps when—they reacquire congressional power. The question is doubly relevant with two more years of guaranteed Democratic White House control.
