it's been ages since I've seen someone trot out "name the trait" or ntt, so forgive me if I'm a bit rusty.
ntt is a form argument that devolves to the spectrum fallacy or line drawing fallacy. basically, it is clear that humans have a set of traits, and chickens have a set of traits, and we can create a human-chicken spectrum. being unable to point to which part of the spectrum you go from human to chicken or vice versa, being unable to draw a line, does not negate the fact that people are not chickens and chickens are not people.
I think a lot of people stopped listening to the rad libs like Maddow and became disaffected from the Democrats since then. those folks are (at least around me) engaging in more radical acts of resistance than the marching-and-shouting that dominated the public actions of that time. so while buttegieg probably hasn't shifted much, and might think he's still talking to those same people, many of them are no longer listening.
