Decriminalize voting rights. Make it automatic for most incarcerated people to have their right to vote returned to them when they have been released. The current situation with so many states being locked by gerrymandering has led to an almost deadlocked congress.
Why is this important?
The more conservative voters increase the power of their vote when they imprison Blacks. Unless states make it simple or simply make it automatic to restore the right to vote, incarcerating black people increases the power of the conservative and white people's vote. It has been impossible or very difficult to restore one's voting rights. Any party that gains a majority can play to white voters to gain a strong hold on that town or county's voter because the justice system is weighted so heavily towards incarcerating Blacks.
