Politics: Taking a guess at the 2012 electoral college outcome

Method:
1. Using the RCP state poll averages for data (O, R)
2. R1 = R*1.01 adjusts for tendency of polls to under-sample Republican voters - this is a debated assumption about systemic error in polling
3. und = O - R1 this is the percent undecided voters
4. O1 = O + (und*0.3333) and R2 = R1 + (und*0.6667) accounts for the debated assumption that undecided voters break 2-to-1 for the challenger
5. O1 + R2 to check to see if the numbers add up to 100%
6. O1 - R2 yields the final vote in that state; a negative value means Gov. Romney wins that state while a positive value means President Obama wins that state
7. EV is the electoral vote value of the state
8. O-EV and R-EV gives the various electoral college totals for the candidates if they hold/lose that state.

Result: President Obama 271 Gov. Romney 267
