2024: climate change has caused singnicant portions of the West Coast to become threatened by rising ocean waters, and the Beenie Bros of coastal northern Cakifornia and Oregon flock to Wyoming's Yellowstone National Park to reconnect with nature, causing the state to form a block in the new blue wall running from New Mexico through Colorado and now Wyoming 1!2!2!!
Though I suppose that kind of mass migration has a non-zero chance of happening.
Well, it happened in Vermont and to an extent Colorado. It's not like the people in those states who kept them red just randomly changed their minds, the states' populations fundamentally changed. Always possible, I guess.
In Vermont, the people who were there previously did change their minds, to some extent.
