Charles Pierce, on the notion of Democrats building a strategy based on what Trump might say about them:

If the Democratic Party tries to temper its rhetoric based on whatever the most recent egregious lie has emerged from the presidential* gob, the Democratic Party is going to have a nervous breakdown. The president, because he is both corrupt and something of a dunce, will say what he's going to say regardless of how temperate the Democratic response is. Sometimes, blunt instruments have to be met with blunt instruments.

Pierce is writing in reference to a debate over whether Democrats should explicitly call out Brian Kemps theft of the Georgia gubernatorial race, but the same holds true for any other debate, including questions of whether Nancy Pelosi should be Speaker come January.
