I have to agree with Dion on this one. Even states that are fully controlled by one party have millions of people who voted the other way living in them. You'd have to physically relocate at least half the population to make it remotely feasible. And it would have to be forced relocation because most people aren't interested in just leaving behind their hometowns, jobs, friends plus anything else they've worked to build. Sounds to me like massive government overreach.
Maybe. But as we see California, SF etc... woken themselves in to a dystopian shole, only the true believers will remain. The rest of us will become redder. The "migrants" much like Italians will assimilate and become just another white group. Asians are now becoming considered white-adjacent because the left cannot explain why they are the most successful immigrants who do not seek or need their handouts. The groups who do well have the strong family structure. A dad and mother in the home. THAT fact alone is the leading indicator of what group will continue to fail. Destroy their family structure and you will continue to guarantee their failure. The left pefected that strategy.
