You could be right but I don't know. Let's look at some numbers. Wyoming is the least populated state with 577k people. Trump beat Clinton by a 46% margin in 2016. If you can find a population that is 80% likely to vote for Democrats you can shift the state to roughly even by bringing in about 330k people. Let's call it 400k to be safe. At $10k a move that would cost $4 billion. That gets you two Senate seats plus some house seats and EC votes for a fairly long time frame. What's the return on investment from other methods like get out the vote campaigns, etc?
