Politics: Electoral College Forecast for Nov 2012

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 281 Gov. Romney 257

Poll pros who really do this seriously:
538 (306-232, Obama)
electoral-vote.com (281-206, Obama, 51 too close to call)
electionprojection.com (290-248, Obama)

I'm just a "blogger in pajamas" but why should they have all the fun?

The reputation of some pollsters is on the line.

Today, a poll in Michigan has Romney up one while everyone else has Obama with leads of various sizes. A Republican presidential candidate has not won Michigan since 1988. Thus, if this pollster is right, there is a huge Romney wave out there. There is a poll that is a few days old on Pennsylvania voters that has it tied. Pennsylvania has not gone to the GOP also since 1988. One pollster has Wisconsin tied and Wisconsin hasn't gone Republican since 1984.

It is entirely possible that these pollsters are outliers and Obama's situation is perfectly fine in the "midwestern firewall" (the above 3 mentioned states) and thus he is on his way to a narrow but clear re-election. But if these outlier pollsters have detected a shift, it is likely that it is a nation-wide shift given that these three states are traditionally Democratic.

In summary:
(1) The national poll data, as is, suggests a close popular vote race and probably Ohio as the decider. It plays out thusly: Romney gets the Atlantic 3 (Florida, Virginia, North Carolina) and 248; Obama gets the Midwest Firewall (Pennsylvania, Michigan, Wisconsin) and 247; Romney and Obama split the Swingy 4 (Colorado, Nevada, New Hamphire, Iowa) yielding at least 10 and as high as 15 electoral votes for each side; leaving the election to Ohio and its 18 electoral votes to decide the Presidency.



(2) If some of the midwestern firewall is actually in play and Romney actually breaks through (for example Wisconsin) then the vast majority of the pollsters will have egg on their faces. Under this scenario, Romney will probably also win Iowa, Colorado and New Hampshire that are already more favorable to Romney. In fact, a Wisconsin/Iowa/Colorado/New Hampshire combo makes up for the loss of Ohio.


(3) If the state polling data is correct, there is no under-reporting of GOP strength and the undecideds go 50/50 in the final days then the result is an easy re-election.
