I hate this map, do you know why?

It makes people feel like their vote doesn't matter compared to these few, and that's not how any of this works.

All this map says is that poll watchers and statistical analysis cannot predict enough of the swing for people in these counties. https://twitter.com/appelletier/status/1322918034554658821

Your vote and the statistical predictability of it makes these votes APPEAR more important, but they're not. They're just as valuable as the next county. Thanks to a stunted electoral college (and the EC per se) they'll probably count more than those in some states but not always

Theoretically the most valuable votes are in Wyoming, but in reality Wyoming homogenaity makes individual votes less valuable overall.

ALWAYS ask what the numbers want you to think.
Then ask if it makes sense.
Manipulation is the whole point.

If we let poll watchers and analysts predict the outcome of elections WE WOULDN'T HAVE HAD TO LIVE THROUGH THE LAST FOUR YEARS.
