You are one of the dumbest people on earth, my district is literally a majority white district. Your conspiracy theories are laughable and should have no place in a society that cares about facts.
This has been happening for years.
Ilhan Omar is the most obvious example. A large number of relatively recently arrived Somalis will elect only a Somali to Congress in that Minnesota district.
This is much more subtle, but just as bad, in many other parts of America.
