it’s still arguable that Republicans have unfair representation in the Senate and EC
LOL, wut? There’s nothing arguable about that. Republicans very definitely have an unfair senate and electoral advantage entirely related to being more popular in less populated states (which, with the notable exceptions you’ve highlighted, tend to also be more rural).
You’re cherry picking top ten and bottom ten like the whole swath of states in between don’t also have unfair allocation and thus don’t matter, while being pretty inconsistent with your battleground state definitions to suit your sorting needs (NH is blue because it only voted R once in 30 years, while every battleground you listed has the same history, and red Florida and Ohio have been 50/50).
While your point about population vs. density is correct, everything else seems to be trying to muddy the waters about the EC rather than just point out an interesting factoid or offer a pedantic correction. There’s no serious argument that the EC isn’t unfair from an individual voter perspective and biased toward one side from a national perspective.
