Read the Research & Findings

Forecasting models developed by prominent political scientists give a slight edge to Barack Obama to win the popular vote over Mitt Romney in the 2012 US presidential election, with 8 of 13 polls giving Obama the edge over Romney. On average, the models predict Obama will receive 50.2% of the two-party popular vote. For comparison, in 2008, Obama received 53.7% of the two-party popular vote.

Five of the 13 models predict a modest to close popular-vote plurality for Barack Obama, though three of these are on the cusp of predicting a tossup; five predict a modest to close popular vote victory for Mitt Romney; and three regard the election as a tossup. The forecasts range from predicting a 53.8% vote for Obama to a 53.1% vote for Romney.

All of the predictions appear in an election-themed symposium in the October issue of PS: Political Science and Politics, a journal of the American Political Science Association (APSA). The forecasts are based on different combinations of statistical and historical data and differ in their complexity and how far in advance their predictions were made. The earliest forecast was made 299 days in advance while the latest was made 57 days before the election. Together, these forecasts use a range of approaches and indicators that are critical to understanding national electoral processes and the dynamics at work in US presidential elections.
