2004 Pre-election RV/LV Polling
Trend Analysis
The
national pre-election poll, after adjusting for voter turnout and undecided
voters, reflects the True Vote.
RV polls include newly registered voters.
The final 15 RCP polls were likely voter polls (LV),
a subset of RV polls.
Earlier polls were a mix of LV and RV.
In 2004, Democratic new voter registration dwarfed
that of the GOP.
There were 22 million voters who did not vote in 2000
(approximately 15 million were first-time voters.
Therefore, final RV polls had to be more accurate
than LV polls.
Kerry led the pre-election polls in August, fell
behind in September and rebounded in October.
Kerry led in the 31 RV polls by 50.1-46.8% after
undecided voters were allocated.
Bush led in the 102 LV polls by 49.2-49.0%.
The majority of new voters (60%) were Democrats.
In 2000, 110.8 million were votes cast and 105.4m
recorded.
Gore won by 540,000 recorded votes.
In 2004, 125.7 million were cast and 122.3m recorded.
Given 1.25% annual voter mortality, 5.5m Election
2000 voters died prior to 2004.
Assuming 98% turnout, 103.2 million Election 2000
voters returned in 2004.
Approximately 3.2 million of the 103.2m were
returning Nader/other voters.
Therefore, there were approximately 22.5m (125.7-
103.2) new voters in 2004.
Kerry won 13.3m (59%) of 22.5m new voters, Bush had
8.8m (39%).
Kerry won 2.0m returning Nader/other voters; Bush had
0.4 million.
According to the National Exit Poll,
10% of Bush 2000 voters defected to Kerry
8% of Gore voters defected to Bush.
Kerry had 91% (47.3 of 51.9m) of returning Gore
voters and 10% (4.8m) of returning Bush voters.
Bush had 90% (42.8m of 47.5m) of returning Bush
voters and 8% (4.2m) of returning Gore voters.
Kerry had 67.4m
(53.6%) = 13.3 new+ 2.0 Nader + 47.3 Gore + 4.8 Bush
Bush had 56.2m
(44.8%) = 8.8 new + 0.4 Nader +
4.2 Gore + 42.8 Bush
Kerry
had 52.0% in the unadjusted aggregate state exit poll (WPE method).
The final 15 RCP national poll average had Bush
leading by 49-47%.
The final Gallup poll was an identical 49-47 before
it was adjusted for undecided voters.
Gallup
assigned 90% of undecided voters to Kerry, so the final Gallup poll had the
race tied at 49-49%
Now let's compare the True Vote result to the
pre-election national polls.
As per Gallup, the final 15 LV poll average, adjusted
for undecided voters, was 49-49%.
But the LV polls did not sample newly registered
voters.
The Election Model utilized 18 final polls, split
equally between RV and LV.
After allocating 75% of undecided voters to Kerry, he
led by 50.9-48.1%
Based on the 122.3m recorded vote, Kerry won by
62.3-58.8m
But the projection did not include the 4.0m uncounted
votes.
Assuming
that Kerry won 75% of the uncounted votes, add 3.0m to his total and 1.0m to
Bush.
Kerry's margin becomes 65.3-59.8m (51.9-47.6%).
That's within 0.1% of the unadjusted aggregate exit
poll.
The
pre-election LV polls, adjusted for new (RV) voters and undecided voters,
matched the Election Model.
But the Election Model did not anticipate that
5-poll
moving average projection trend
75% of undecided voters allocated to
Kerry
Other 3rd party projection: 1%
