Small states will likely form coalitions with neighbouring states with whom they share culture and values. Texas, California, Florida, and New York might be independent, with nearby coilitions of states falling into their spheres of influence, or they may be the dominant power in a coalition of states.
It would be interesting to see what becomes of the states in the Midwest and the Great Basin. None of them have the economic power to stand on their own, and they will be reliant on having good relations with States that have ports.
Border disputes and tensions will be widespread, and the state-lines we know today will likely be completely redrawn. It’s likely too that many States will be facing their own internal succession movements from regions on the other end of the culture wars. Not to mention foreign powers pursuing their interests in the remains of the United States. The only certainty in this hypothetical future is that is will be a big, bloody, mess.
I mean, it could be a shitty disfunctional country with a very poor QoL, but still an independent country.
