(that's the Romney plus percentages) gs
According to their analysis, President Barack Obama will win 218 votes in the Electoral College, short of the 270 he needs. And though they chiefly focus on the Electoral College, the political scientists predict Romney will win 52.9 percent of the popular vote to Obamas 47.1 percent, when considering only the two major political parties.
For the last eight presidential elections, this model has correctly predicted the winner.
Their model correctly predicted all elections since 1980, including two years when independent candidates ran strongly, 1980 and 1992. It also correctly predicted the outcome in 2000, when Al Gore received the most popular vote but George W. Bush won the election.
The study will be published this month in PS: Political Science & Politics, a peer-reviewed journal of the American Political Science Association. It will be among about a dozen election prediction models, but one of only two to focus on the Electoral College.
While many forecast models are based on the popular vote, the Electoral College model developed by Bickers and Berry is the only one of its type to include more than one state-level measure of economic conditions."
The polling numbers at the end of Sept suggest a 6.3% Romney win.
The state by state economic model suggest a 5.8% Romney win.
