Ruth Bader Ginsburg's death reshapes competitive Senate races

"The possibility of filling Justice Ginsburg’s seat has upended Senate races from North Carolina to Arizona, giving an already deeply polarized electorate a new focal point. Ms. Collins, a Republican, has already said she will oppose any effort by President Trump to rush a nominee through.
