Mathematical Model: Kerry 289 Bush 223
This predictive map was made using the following assumptions.
- Voters who already have made a choice will stick to it
- The undecideds will break 2:1 for the challenger (Kerry)
- In states where Nader is on the ballot, he will get 1%; otherwise 0% (was 2.74% nationally in 2000)
- The minor candidates such as Badnarik, Cobb, etc. will get 1% of the vote (was 1.01% in 2000)
The numbers given for Kerry and Bush in the pop-up boxes include the undecideds.
