I think you did the electoral math wrong, however. Sandoval should only be winning with 289 EVs, per my calculations.
2020 reapportiomment has been incorporated into this timeline.
Exactly. I haven't done the map for that, of course. Not sure I'd know how.
In the image url for the map, there are 3 numbers after each state. The second is the number of electoral votes that the state gets. You still have to calculate the totals manually, but you can at least get the map you post to show a 41 in TX, or a 56 in CA, etc.
