a fun thing about conservative SCOTUS deference to state legislatures is these are the same justices that have permitted the kind of hyper-partisan gerrymandering that has allowed wisconsin republicans, for example, to lose the statewide vote but win a supermajority of seats.
"oh you want authorities to count all the votes? well, win a majority and change the law. oh, we& #39;ve allowed our fellow travelers to turn voting minorities into unbreakable legislative majorities? weird how that happened"
and of course, as we& #39;ve seen in wisconsin and michigan and north carolina, if you manage to elect a governor as a counterweight to the gerrymandered minority legislature, that legislature will just strip the governor of power
muster a supermajority of your fellow citizens to amend your state constitution to expand the franchise? well, as we& #39;ve seen in florida, the republican governor and legislature will just invalidate it with a poll tax.
