Today’s Democratic Party will be a little fractious, but I don’t worry much about that. It’s inevitable, especially with the recent influx of new members who come from diverse backgrounds, experiences, and political traditions. And in most instances it is a positive thing, especially when Democratic legislators and the larger coalition resisting Trump keep in mind that the main — the strategic — task facing them is to thump Trump next year. From my experience in a much smaller pond, keeping a lid on things may succeed for a while, but will come back to bit you in the longer run.
