Incredibly thoughtful, detailed analysis of what motivates "lefties" and "liberals," and an excellent start for understanding and respecting each other's analytical strengths and weaknesses if we're going to work together and build a much larger (and vastly more effective) coalition:
A productive peace process for the intra-party war would merge these insights, advancing a practice that would help defeat the Republican Party while keeping Democratic leaders on their toes. We could call this practice “vigorous critical loyalty.” Vigorous critical loyalty would work by separating the times for vigorous party loyalty and the times for vigorous internal criticism...
...
Most importantly, vigorous critical loyalty could help rebuild trust. Primary challengers that win — and even incumbents that are forced to hold back a primary challenger — become closer to the people they represent. To have an issue emerge from a trusted outside group and then have that issue enter the mainstream of the party is to build loyalists’ trust in that outside group while building populists’ trust in the party. With the periphery of the party showing loyalty in the general election and the center of the party opening up to new ideas and leaders, the distinction between the periphery and the center is blurred.
This is how two tribes could eventually merge into one without either side compromising on their ideals and loyalties. Reading Twitter today, it may seem like a longshot. But I take hope from a point Washington Post assistant editor Elizabeth Bruenig raised at a talk earlier this year: “You don’t argue with people who are nothing like you… you argue with people who are almost like you… [Arguing] is a pretty good sign of the possibility of coalition.”
