Political prisoners

Senate Republicans are trying to overturn last year's state law that counts prisoners at their home addresses for electoral purposes (mostly in NYC and other heavily Democratic cities), and not where the prisons are located (mostly in GOP districts upstate). They seem to me to have a pretty good case, and it's also a potential win-win politically. They can tie the issue to redistricting reform, and if that means the reform goes nowhere, it won't break their hearts.
