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. Let’s hope that these tools become even more prominent in political journalism and punditry.
