If the Palin pick has done nothing else, it's got Obama
supporters second-guessing themselves. Here's Nate Silver at FiveThirtyEight trying to make
sense of the latest poll numbers:
My horse sense is that the numbers are affected to some
degree [by] response bias. Republicans, especially evangelical
conservatives, are pumped now, after having been indifferent toward
John McCain for most of the election cycle. They may be picking up
the phone when a pollster calls when they had been screening out
the call before, perhaps to the extent that they are biasing the
sample. . . .
It seems plausible to me that some segment of conservative
Republican voters had effectively been in hiding from the
pollsters, either embarrassed by the performance of George W. Bush
(and therefore disengaged from politics), or embarrassed to
disclose to pollsters that they support him. Suddenly, with the
selection of Palin, there has been a jolt of energy within this
group, a release of pent-up frustrations, and they are coming out
of the woodwork. If this is the case, then perhaps the
partisan composition of the electorate had never shifted as much
from 2004 as it has appeared to; rather, the
conservatives were either reluctant to identify themselves as
Republican, or reluctant to take a pollster's calls in the first
place. (Emphasis added.)
Never mind Silver's guesswork about "response bias" -- he is a
30-year-old
baseball statistics buff and an amateur at political
analysis --what's noteworthy is how the Palin pick has punctured
his heretofore insuperable confidence in his own predictions of an
Obama victory in November. The marketers of Hope were always, at
some level, dependent on their supporters' notion of inevitable
triumph. And the wild-card choice of Palin (and the conservative
enthusiasm for her) has seriously undermined that notion.
