It’s a national map with all the (pending and enacted) voter suppression laws collected in one place.
If you click on your state, there’s specific information on voting. For those of us who live in “shame” states, it’s information on how to jump through the hoops and vote a first-class (rather than “provisional”, or second-class) ballot.
I like the states with the big, black V. Those are the states where the governor vetoed voter suppression legislation: Minnesota, Missouri, Montana, New Hampshire and North Carolina.
