The war on voting has been going very well for Republicans.
The key victory was Shelby v Holder (
https://en.wikipedia.org/wiki/Shelby_County_v._Holder). That was a decision where the conservative supreme court legislated from the bench to favor their political team. It said federal courts must assume states mean no harm when they restrict voting rights, regardless of the facts or their history.
Some lawyers can talk about it, but to a regular person it sure seems like they rejected their own principles of defer to the legislature, original intent, textualism, or whatever. They also chucked out the legislature's fact finding and inserted their own. The result was a decision that the 14th amendment doesn't apply to voting.
Now the official republican position is creating artificial barriers to prevent democrats from voting is good, smart politics. Poll taxes are back. SQL queries to delete democrats are also popular.
The North Dakota one is quite a thing. The USPS won't deliver mail to the tribes, so they use PO boxes. The law requires your id have a residential address, not a PO box. Poof, 70000 native americans can't vote without paying a poll tax.
