2008 Election Model (
EM) assumes as a base case that a fraud-free election is held today — and that current polls reflect the true vote. The state model projects Obama will win the Electoral Vote by
367–
171. The final projected vote share is Obama-
53.1 McCain-
44.9% Other-
2.0%. The
state poll aggregate vote share matched the
national average tracking poll to within 0.2%.
In May, the
2008 Election Calculator (
EC) projected that Obama would win the
True Vote by
71–59m (
54.1–
44.7%).
For the
2008 EC to
match the
EM, its estimate of returning 60.5m-Kerry and 51.6m-Bush voters
had to be accurate.
The
EC used
12:22am 2004 NEP vote shares to calculate the projections.
In other words, the 2008
EC and
EM confirmed that
Kerry won a landslide (see below).

The 2008 Election Calculator Model confirms the 2004 and 2008 Election Model (and vice-versa)
In May 2008, the
2008 Election Calculator projected that Obama would win the True Vote by
71–59m (54.1–44.7%).
Checking the 2004 Election Calculator (EC) True Vote and the 2008 Election Model (EM) Projections
On Nov.3, 2008 the following test was performed:
The
12:22am 2004 Preliminary NEP vote shares (
13,047 random sample,
1% MoE...link below) were input to the
2008 EC.
In the
2008 EM, 75% UVA and 3rd party 1% share were input to match
2004 EC assumptions.
The resulting
2008 EC calculated True Vote projection closely matched the
independent 2008 EM Polls-projection (to within 0.2%).
Therefore, the
2004 EC vote shares and
weighting mix are also confirmed and therefore must be fairly accurate.
The 2008 EC could only be accurate (and match the EM), if the input estimate of returning 2004 Bush and Kerry voters was also accurate.
The model estimates 60m returning Kerry voters and 51.6m returning Bush voters.
Given a 75% UVA and 1% to Other, the EC projects Obama will win by
78.3–
63.8 million votes, assuming a fraud-free election.
Note that the base case EM is 60% UVA and 2% Other
