If Obama's lead holds up in Florida, Silver's election model will have correctly predicted the winner in all fifty states of the presidential election. In addition to that, he correctly predicted the winners in senate races in Maine, Massachusetts, Indiana, Ohio, Florida, Missouri, Wisconsin and Nevada.
Goldberg correctly predicted that the sun would rise in the east on Wednesday.
Goldberg can say all he wants; Silver's reliance on numbers - empirical evidence unhampered by political ideology - makes his model the most accurate determiner of these elections.
Goldberg should pack up his ouija board and magic eight ball and concede the job of picking winners and losers to Nate Silver.
