the democrats want muslim americans and chinese-americans to vote for them, which fundamentally fucks up their foreign policy to an unworkable mess and functionally makes them unelectable and renders them incapable of governing.
america needs to be able to fight it's enemies, and it can't do that if the natural governing party relies on them as a part of their voting coalition.
this is one way that empires collapse. it seems oddly similar to how christianity destroyed rome from the inside.
