How the Election Will Be Called

My print column examines how the major news networks and the Associated Press will call the election on Tuesday night. The AP — plus ABC, CBS, NBC, CNN and Fox, which, like The Wall Street Journal, is owned by News Corp NWSA -0.09% — form a consortium, called the National Election Pool, to gather and share information that they will use on election night to call states for President Barack Obama or Mitt Romney. That information, collected by Somerville, N.J.-based Edison Research, includes telephone polling of early voters before Election Day, plus exit polls on Tuesday and sampling of precinct vote counts after the polls close.
