The first section is to enter the results from a media poll, including % of democrats, % of Republicans, % of Independents, enter % Obama, % Romney, % Undecided, % Others for each of these groups ( i.e. demorats, Republicans, Independents)
The second section is to t adjust the % democrats, % Republicans, % of Independents to match a more realistic elections turnout for each group. The worst case scenario would be democrats + 3% over Republicans but the most probable scenario is % republicans = % democrats on elections day. Make sure that when you do the adjustments for each of these group that they add to 100%.
The third section is the assignment of the % of undecided to each Romney and Obama. So you need to enter the % of undecided for Romney and those for Obama. Historically the undecided go 2:1 for the challenger
