A key part of the #VotingRightsAct, the 1965 #CivilRights landmark, appears at risk after arguments in a case from #Louisiana before #SCOTUS on Wednesday. It is at least possible that the court will rule unconstitutional a provision allowing states to use #race as a factor in drawing electoral maps.

But even if the #law survives its encounter with the justices, it faces a second significant challenge, from #NorthDakota. The court will consider whether to hear an appeal in that case in November.
