"2012 was the First Moneyball Election"
Barack Obama’s victory tonight is also a victory for the Moneyball approach to politics. It shows us that we can use systematic data—economic data, polling data—to separate momentum from no-mentum, to dispense with the gaseous emanations of pundits’ “guts,” and ultimately to forecast the winner. The means and methods of political science, social science, and statistics, including polls, are not perfect, and Nate Silver is not our “algorithmic overlord” (a point I don’t think he would disagree with).
But 2012 has showed how useful and necessary these tools are for understanding how politics and elections work. ...

The forecasting is only as good as the input. The disagreement was over the accuracy of the state polls. It turned out that D+6 or D+8 better reflected the turnout than D+3. However, that was a judgment call and not the result of mathematics.

Oh, joy. IOW, he's saying the pundits will be replaced by the number cruncher. He makes it sound like this is a good thing. Farther we move from ideas to numbers or 'guts', the worse the health of politics.
