New analysis by a respected political scientist indicates that there is a
92% probability that Obama will maintain his lead in the polls and win the
election. Small wonder Republicans are
worried.
Drew Linzer is an Assistant Professor of Political Science
at Emory University. He has a blog VOTAMATIC that provides forecasts and polling
analysis for the 2012 presidential election.
Linzer tracks the most recent state polls and then uses a statistical model to project the
likely outcome of the election under different scenarios of how the poll results might change.
In a post today, Linzer provides some analysis of what his
model suggests is likely to happen between now and Election Day. Specifically, Linzer looks at the probability
that Obama can maintain his lead in the polls in key battleground states and
win the election. Linzer ran 10,000
plausible “states of the race” scenarios in all 50 states.
Linzer has some very bad news for Romney. Linzer’s statistical forecasts of the most
probable outcome gives Obama has a 92% chance of winning the election with a
median of 347 electoral votes.
Even when
Linzer plugs in some very favorable assumptions for Romney, the outcome doesn’t
change that much. Obama still has a 62%
chance of winning.
Of course, the Republicans will argue that Linzer’s analysis
is based upon state polling and that the state polls this year are flawed. Linzer took a look at that. He finds that the polls this year and
behaving about as expected given their sample size. In fact, Linzer says: “What is actually
astounding about the polls this year is how well they are behaving, compared to
theoretical expectations….It turns out that most polls have been exactly where
they should be – within two or three points of the model estimates. And that’s
without any correction in my model for “house effects,” or systematic biases in
the results of particular polling organizations.”
As I said, that’s all bad news for Romney and the
Republicans. We can only hope that
Linzer is right.
