The Dissenting View: Forecasting Odds in Favor of a Romney Victory

Although most forecast models are pointing towards an Obama victory, Romney supporters may be encouraged to know that there are forecasts predicting a Romney win instead. Dylan Matthew’s piece discusses five social science studies concerned with forecasting the election, including one study by Michael S. Lewis-Beck and Charles P. Tien as well as the Douglass Hibb’s model, both of which forecast a Romney victory. Lewis-Beck and Tien estimate with 77% certainty that Romney will get 51.8% of the vote, while Obama will finish with 48.2%. The Hubbs model estimates that Romney will win 53% to Obama’s 47%.

Why Do We Care About the Odds?

In theory, an election would mean that we would all simply read up on the candidates and the issues, cast our votes accordingly and then, find out the outcome when it’s over. But the reality is that just as much as we are a country watching the candidates, analyzing the issues, and getting ready to vote, we are a country anxiously watching ourselves. We are consuming a daily diet of polls, ads, fact checks and even minute-to-minute Tweets, presumably aimed at satisfying our craving for the freshest glimpse of our collective selves in the mirror as we inch closer and closer to election day. This race between Barack Obama and Mitt Romney is so close, that with just a couple of weeks left until election day, it’s still incredibly difficult to say who will win. And that’s the excitement of it all, and yet, that’s  also the rub. The truth of the matter is that we care about nailing down the odds, pinning a set of numbers on this election, because honestly, the suspense is killing us and just about any semblance of predicability would give us at least a little comfort.

Besides a possible relief for pre-election jitters, for some, an idea of what the odds are surrounding this election may influence decisions on everything from whether or not to donate money or time to a candidate’s campaign to even whether or not to vote at all. Just remember–even the best forecasts make no claim of absolute certainty. So hopefully, you’ll make the decision to vote in this historic election–regardless of, in light of, or in spite of, the odds that your candidate will win.
