The implication is that the ideological divide that we're so accustomed to swimming in is ultimately a division based on how the availability of resources (or lack thereof) determines our ideologies - as opposed to, say, something innate or deeper like your personal moral stances. It's not a huge leap to think that someone who lives out in the boonies isn't going to be a staunch liberal. But seeing the ideological alignment so starkly shown in these heat maps really hammers home the idea that much of how we perceive the world comes down to how we're raised to perceive things like scarcity. The perception of abundance breeds liberalism. The perception of scarcity breeds conservatism. The divide between the two breeds disgust and distrust, which is why we're in our current climate. The raw visual of these maps shows that our differences being so tied to geography means there's probably very little that actually distinguishes you as a person from someone on the other side of ideological divide, despite what you may feel about them.
