There is some great theory around moderation which goes far beyond this piece. David Lakoff's book "Don't Think of an Elephant" is a classic.

Moderation is rarely a choice. There's an old expression, "The only thing in the middle of the road is roadkill." It's not saying that moderates are extinct or undesirable. Rather, left and right political views mostly come from a history of life experiences that drives people either towards empathy for strangers or towards fear of strangers. The combination of these worldviews and the human desire for having a community or clan drives people into parties in opposition to each other.

For most moderates, their experiences instead drive them to prefer either worldview depending upon which issue is being considered. Their experiences are not totally based on seeking safety or showing empathy. They are not middle of the road on most issues, but have a diverse set of opinions. Their opinions are diverse enough to not feel fully accepted into either party and to adjust their own views into alignment, unless their country has a middle party. This seems to be what Graham calls deliberate moderates.

There are also moderates who become moderate because nuance is important to smart policy. Fully left or right ideas both tend to overshoot evidence-based decision-making. I believe this is what Graham refers to as accidental moderates. However, the roadkill metaphor still applies because even accidental moderates still have life experiences that lead them to a worldview as well as the human desire to belong to a group. Even those who apply past policy-based evidence to develop a nuanced view will have a human desire to try to fit themselves somewhere into the partisan political landscape of their environment. It's not easy being the odd one who doesn't fit.
