As of late last month, fourteen states had passed twenty-two new laws restricting voting. Sixty-one other bills are still moving through eighteen state legislatures, and nearly four hundred such bills have been proposed in total. There will presumably be many court battles over the new legal barriers to the polls enacted by Republican legislatures across the country. But barring passage of legislation pending before Congress, it’s the Supreme Court that once again holds the cards when it comes to the success or failure of those lawsuits.
