Always remember that policy universally is promoted to further the agenda of a given party! Many republican politicians opt for the abolition of early/absentee voting, and democrats the opposite. Bear in mind that these policies are not just ideological rhetoric, but political play, intended to benefit the ruling party rather than the wider people.
As someone who voted blue, part of my motivation to not do it on election day was to avoid being harassed by Trump's poll ~~watchers~~ intimidators.
I can't say whether the conclusion you've drawn from the maps is right or wrong. But I can say that the analysis is probably incomplete. Because does that pattern hold out in other elections too?
Yeah, I understand that, and I’ve made the conscious decision to remove the commentary as I’ve realized my error. I am interested in how this pattern may hold up in prior elections. I’ll have to do some more looking.
