But, oddly enough, those very large cities aren't so large anymore. And yet the vote tallies from those cities remain large enough to shift the entire state into the Blue Zone.
That’s the best part - the population is drastically reduced but the number of voters stays the same
Not really; even if they’re keeping them in the Blue Zone, the states themselves are losing electoral votes due to those population losses. It certainly is less damaging in terms of the electoral college; it has forced Dems to try to carve out “red” states to come up with more than half of the electoral votes (and is getting worse for them with each census).
