Actually, I read that conservative counties had an average 35% voter participation rate, while the liberal ones had a 74% rate, for what it’s worth.
I don’t know what the participation rate was. Although I do know that Conservative/GOP motivated voters is below where it ought to be. Too many nutters turned out in 2018/19, but because of the gerrymandering in VA, you’d have had to have a disproportionately higher % of GOP voters to have prevented the gerrymander from working in key districts that narrowly “elected” Dems.
