Presidential Forecast - 8/6 - Delayed Reaction

WE'VE MOVED! Democratic Convention Watch is now at http://www.DemocraticConventionWatch.com

Obama leads 299-239, a gain of 2 EVs for McCain since the last forecast, and the first time Obama has been below 300 EVs since June 20th. McCain picked up some movement in Florida and Ohio, and anytime a large state changes category, it's worth about 1 EV in the overall numbers. On the other hand, NBC did their monthly update, moving 3 states in Obama's direction, including Iowa finally out of Tossup.

Remember that state polls lag behind national polls, and some projections don't update as frequently as others, so the projection could be better thought of as an average over the last 3 weeks or so.

One other note about NBC's projection. One of the things they look at is whether the campaigns are contesting a state. In NJ, 3 of the last 4 polls show a 10 point lead or less, so one could argue it should be Obama-Lean. But McCain is not contesting the state, so it's very unlikely to shift. That's one difference between the CNN and NBC type projections, and the purely poll driven projections.

Please also check out our Senate Forecast and House Forecast.

Map showing consensus of sources. This table will show a state Blue or Red if a majority of the sources show it Leaning or Solid for that candidate. No changes from the previous map.

Note: Only 2 states have shifted categories on the consensus map since early June and not shifted back:
6/18 FL: McCain -> Tossup
7/9 NM: Tossup -> Obama

Of special note is NC, which has shifted 4 times between McCain and Tossup.

Unanimous solid states, not shown in the table below:
Solid Obama: CA, CT, DC, HI, IL, MD, NY, RI, VT - 138 EVs. Note: MA is no longer unanimous Obama (Elec-Vote and RCP have it as OL), but has not been placed on the chart at this time.
Solid McCain: AL, ID, KS, NE, OK, TN, UT, WY - 50 EVs. Note: KY is longer unanimous McCain-Stronge (RCP has it at ML), but has not been placed on the chart at this time. (All numbers, however, are correct).

The sources are sorted by each projection's estimate of Obama's Electoral Votes (Algorithm at bottom). The states are sorted by the number of electoral votes.

Here are the states that span 3 categories.

  • Indiana: 4 at Tossup, Rasmussen at McCain-Strong.
  • Iowa: Two at Obama-Strong, CNN still calling it a Tossup. Only July poll shows Obama up by 10.
  • Minnesota : 4 at Obama-Strong, CNN at Tossup
  • New Mexico: 1 Projection at Obama-Strong, 3 at Tossup. Only polls in July has Obama up 6. This used to be on the 3 category list, but spanning Obama-Lean to McCain-Lean.
  • North Dakota - CNN at McCain Strong, 3 at Tossup.
  • Pennsylvania: OpenLeft at Obama-Strong, 2 at Tossup. Obama averaging up 7 in 3 late July polls.
  • South Dakota: EV.com at Tossup, 3 at McCain-Strong
We're purposely ignoring Maine and Nebraska CD splits for now to keep things simple. We'll add them in later if we need to.

The overall projection is just a straight average of each projections' estimate of Electoral Votes (EVs) for each candidate. For each projection other than FiveThirtyEight, we give Obama 100% of the EVs in a state that is solid for him, 80% of the EVs for a leaner, 50% of the EVs for a Tossup, 20% of the EVs for state that is McCain-Lean, and 0% of the Solid McCain states. Exact opposite for McCain. For FiveThirtyEight, we use their overall estimate of Obama's EVs, not the state-by-state categories.
