Historical Analysis Points to McCain Edge

What do you get when you cross a political science college minor with someone who has spent over a decade crunching numbers for sports handicappers… and apply that to this year’s electoral college in the general election for President?

5 McCain Victories
5 with no winner but a McCain edge
1 with no winner but an Obama/Clinton edge
1 Tie

These are not predictions, but instead numbers generated based on historical analysis of each state. Let’s break down each of the 12 scenarios. Click on each link to see the data used for each scenario.

Scenario 1a – 269-269 Electoral Tie
This merely takes each state’s voting history for the past 5 elections and awards the party with the most victories the electoral votes this year. For example, Alaska has voted Republican in the past 5 elections, so McCain is awarded Alaska’s 3 electoral votes in 2008. This scenario does include borderline states, such as Arkansas, which voted Republican 3 times and Democrat 2 times.

Scenario 1b – 199 McCain – 255 Obama/Clinton
This uses the same data as Scenario 1a, but removes borderline states.

Scenario 2a – 278 McCain – 260 Obama/Clinton
Again, we’re using the same data as Scenario 1a, but this time we’re going back the past 7 elections, which includes the Reagan 1980 and 1984 victories in the averages. Borderline states are included.

Scenario 2b – 269 McCain – 102 Obama/Clinton
This is the same data as Scenario 2a, but excluding borderline states.

Scenario 3a – 414 McCain – 124 Obama/Clinton
Scenario #3 takes a look at how likely a state is to vote for the incumbent party versus the non-incumbent party, going back to 1988. In this situation, we are calling Republicans the incumbent party and Democrats the non-incumbent party. Most states are borderline in this category.

Scenario 3b – 42 McCain – 0 Obama/Clinton
This is the same data as Scenario 3a, but removing borderline states. As you can see, most electoral votes are not counted with this method.

Scenario 4a – 438 McCain – 100 Obama/Clinton
This is the same data as Scenario 3a, but going back to 1980. McCain is given a bigger boost with this method.

Scenario 4b – 56 McCain – 0 Obama/Clinton
Scenario 4a data is used, but omitting borderline states.

Scenario 5a – 274 McCain – 264 Obama/Clinton
Scenarios 5 and 6 are perhaps the most interesting, as they combine states voting history by party with their likelihood to vote for the incumbent or non-incumbent party. The race tightens up here, but the edge goes to McCain. Again borderline states are included and this data goes back to 1988.

Scenario 5b – 172 McCain – 88 Obama/Clinton
The same data as Scenario 5a, but with borderline states omitted.

Scenario 6a – 274 McCain – 88 Obama/Clinton
Again, the same as Scenario 5a, but using a data pool going back to 1980, and includes borderline states.

Scenario 6b – 172 McCain – 13 Obama/Clinton
Scenario 6a data but with borderline states omitted.
