Mitt Romney, Donald Trump, and Mike Huckabee are all Republicans, but they are from very different tribes.
Yea, I get that. I just think “tribe” is a crappy term for what are essentially differences in political emphases. “Tribes” don’t have overlap. The groupings you are describing are Venn diagrams with lots of overlap. Hence, “tribe” is a shitty term.
One thing that shocked and horrified my friends about Trump’s candidacy was his fondness for his name in huge gold letters. This was every bit as frightening to them as anything that was in his policies. Why? Because my friends, culturally, are academic types and materially showing off in that way is anathema to the academic culture.
Except when peer-reviewed papers are to be delivered, of course.
