While US-specific in some aspects (political party (self-)filtering), it also looks at things more generally (psychological studies on how humans can form 'tribes' almost spontaneously).
Sad to hear that people so badly over identify with their tribe that they'd rather obstruct solving a problem they care about than to cooperate. Since solving together would be seen as a win for the opposition. This binary, one-up-one-down thinking is pathological and will just produce gridlock.
It's also a lack of trust. A severe one. Even if the two 'sides' had aligned goals sometimes they just don't trust the other that its not some sort of bait and switch.
