Two CU professors reveal the factors contributing to presidential wins since 1980.

Ken Bickers has a crystal ball. But it鈥檚 not shaped like a ball. Flat and rectangular, really 鈥� like a computer screen. Well, actually, it is a computer screen. Still, when the CU-Boulder political science professor stares into it, he says the future is often as clear as a Colorado cobalt sky.

Last summer, Bickers used his crystal ball to predict that Mitt Romney would send President Barack Obama packing by winning 325 Electoral College votes when only 270 are needed for the White House keys. His crystal ball shattered after Obama won 303 electoral votes to Romney鈥檚 206 (not counting Florida). The results surprised him and many political scientists and presidential historians. History has shown when the economy is not doing well incumbent presidents usually lose re-election.

鈥淥ur estimate is that the President鈥檚 campaign efforts, specifically in the battleground states, lifted his vote share in those states by about 5-6 percentage points,鈥� Bickers says.

In the battleground states he says that was enough to produce a win for Obama in all of them, except North Carolina, and to produce close to a tie in Florida.

So where exactly did Bickers come up with his model and why did it work for every election, except for this one, since 1980?

The story begins in 2008 as workers swept up confetti at Invesco Field at Mile High Stadium where President Obama accepted his party鈥檚 nomination for president.

Bickers and Michael Berry, an assistant professor of political science at CU-Denver, had spoken with several reporters who asked if they thought hosting the Democratic National Convention would win Obama Colorado鈥檚 Electoral College votes.

鈥淎t the time we could only speculate but thought it made for an interesting research question,鈥� Berry says.

After the 2008 election, the two men crunched large sets of data from states in each election cycle from 1948 to 2008. The result? Absolutely no convention effect for either party.

But after that project, the two men began to do what professors often do: Think. Specifically, they began thinking about how they might apply all the data they amassed to predict presidential elections.

Berry and Bickers were familiar with other models and the many factors used to project the national popular vote. They say they didn鈥檛 deliberately set out to build something that would differ from existing models, but since the president is elected through the Electoral College, Bickers says it made more sense to construct a model that would let them make state-by-state forecasts.

In essence, the two men see the presidential election as 51 separate contests 鈥� the 50 states and the District of Columbia 鈥� not just one national competition.

One model used state forecasts in 2008, but it only counted change in personal income. Bickers and Berry say that since jobs are often a large focus in campaigns, they opted to add state and national unemployment data to the model.

They also considered party voting in prior presidential elections 鈥� again at the state level 鈥� and how long a party has been in power. But they say economics is key and reminiscent of political pundit James Carville鈥檚 famous line from the 1990s, 鈥淚t鈥檚 the economy, stupid.鈥� In fact, Bickers calls the economic variables 鈥渢he heart of the model.鈥�

鈥淭he surprise to me was the success of the Obama campaign in neutralizing the economic conditions.鈥�

So the model carefully considers unemployment rates in each state from late spring and summer of the election year and compares changes in real per capita income 鈥� people鈥檚 disposable income 鈥� from when the current president was elected to the first quarter of his last year in office.

鈥淚t鈥檚 like the question Ronald Reagan asked in the 1980 election: 鈥楢re you better off now than you were four years ago?鈥� 鈥� Bickers says. 鈥淭he percentage change of income has fallen in more than half of the states. In a normal economy, it would be many fewer states.鈥�

鈥淭he surprise to me was the success of the Obama campaign in neutralizing the economic conditions.鈥�

After they completed the model, Bickers and Berry put it to the history test, applying it to the last eight presidential elections beginning in 1980. The federal government lacked state data they needed prior to 1980, so they stopped at that election year. The model passed with flying colors, correctly classifying the winner in each election, including the photo-finish 2000 election when George W. Bush edged Vice President Al Gore.

Bickers says that particular election illustrates the power of too much time in office, another variable they deem important. President Clinton had served his limit.

鈥淰oters look at how long a party has been in office, and sometimes that works against the in-party,鈥� he says. 鈥淚t happened in 2008 when Sen. [John] McCain ran for a third consecutive presidential term for Republicans.鈥�

But Bickers adds the economy was starting to sag due to the dot-com bubble in 2000.

鈥淭ougher economic times were starting to ripple through some states before the election,鈥� he says.

In 1992 the economy and incumbency factors were again at play. Republicans had held the White House for 12 years, and the economy was growing tepid in many parts of the country.

But 1992 also showed Berry and Bickers that a strong third-party candidate can throw a wrench in their model. While the model correctly predicted Clinton, in that election they also missed 10 states.

鈥淭hat鈥檚 20 percent, basically, and it shows just how significant Ross Perot ended up being,鈥� Bickers says. 鈥淲e鈥檝e puzzled over third-party candidates. We鈥檙e essentially saying people can vote for a Democrat or Republican, but they can vote for others. They did for Perot in 1992 and 1996 鈥� our model misses a lot in those circumstances.鈥�

The two did offer themselves a little wiggle room with the 2012 election because of the amount of time before the election and the number of states where the presidential race seemed close this summer. The latest data they could use came in September before the Nov. 6 election. Things can happen in two months. And some states were near a 50-50 split in late summer.

Minnesota in particular was a head-scratcher for Bickers.

鈥淢innesota hasn鈥檛 voted for a Republican in a long time, but our model has Romney winning it,鈥� he says, which ended up being incorrect.

The model predicted Obama would lose nearly all of the states considered swing states in the election 鈥� North Carolina, Virginia, New Hampshire, Colorado, Wisconsin, Minnesota, New Mexico, Pennsylvania, Ohio and Florida. In fact, he only lost North Carolina, and Florida was not tallied at press time.

Two other states viewed by some as swing states 鈥� Michigan and Nevada 鈥� were predicted to stay in Obama鈥檚 column. This prediction was correct.

After releasing their prediction in the summer of a Romney win, Berry and Bickers say they were glorified and vilified, at once being called the smartest men alive and then accused of trying to sway the election.

For the record, Bickers preferred not to share his party affiliation, and Berry said he鈥檚 unaffiliated.

As for any lessons learned from their prediction project, both say they came away a little wiser.

Bickers says he learned that when there鈥檚 a big thing in the election, there really is a big thing. That thing in this election was the economy.

鈥淭he surprise to me was the success of the Obama campaign in neutralizing the economic conditions,鈥� Bickers says. 鈥淏y doing that, they were able to shift focus to other issues, such as immigration and women鈥檚 rights 鈥� issues where the Democrats enjoy healthy advantages over Republicans.鈥�

He also thinks early negative ads in the battleground states painted Romney as someone who couldn鈥檛 be trusted with the economy.

鈥淎nd Romney鈥檚 stance on immigration may have played a heavy hand in his loss,鈥� Bickers says. 鈥淭he tone of the Republican nomination process put him in a box, particularly with the Latino voters, that he couldn鈥檛 find a way out of 鈥� his kind of harsh, strident position on illegal immigrants.鈥�
