Statistical odds of overall election outcome
Last update on: August 27, 2012
Why are Romney’s chances so low?
- Obama has 201 safe electoral votes. Romney has only 181. Only 12 states (156 electoral votes) could go to either candidate.
- Therefore, Romney needs at least 89 of those 156 electoral votes to win (57%).
- Given current polling in those states & historical polling accuracy, Romney’s statistical chance of getting those 89 votes is only 19%.
