PUBLIC OPINION CHAPTER 9
PART 2
Mr. Westerfeld 9/22-23
BELLWORK
Obama maintains his lead in CNN's national poll of
polls. According to the latest poll of polls, released
Friday, Obama is ahead of McCain by three
percentage points -- 47-44.
The poll of polls consists of three surveys: Gallup
(September 16-18), Diageo/Hotline (September 16-18),
and Big Ten Battleground (September 14-17).
With recent polls showing about 10 percent of voters
still undecided, the debates could prove critical in
deciding the election, according to Paul Steinhauser,
CNN's deputy political editor.
"These debates ... they could be crucial in these
undecided Americans making up their minds. And
those undecided Americans are the ones who are
basically going to sway the election and move it one
way or the other," he said.

Political ignorance is a fact of political life given the
high cost of political attentiveness.


Reading, thinking, participation, social friction, and
pessimism can all be costs of political knowledge
Someone will make the decision
Shortcuts
The trusted other, believe what someone you usually
agree with believes (the opposite is also true)
 Party affiliation or ideology

WHY THAT ISN’T SO GOOD IN A
DEMOCRACY
Issues are often too complex to lend themselves
to simple ideological interpretation.
 Shortcut takers can become victims in political
struggles because they cannot effectively defend
their political interests
 Large numbers of politically inattentive people
means that the political process can be more
easily manipulated by the forces that seek to
shape public opinion.

SHAPING OPINION

Government
Presidents and the Executive branch use polls, focus
groups, planted news stories, and film to try to
persuade the public with propaganda.

MEASURING PUBLIC OPINION
Random digit dialing- a poll in which
respondents are selected at random from a list of
ten digit telephone numbers, with every effort
made to avoid bias in the construction of the
sample
 Selection bias-a polling error in which the sample
is not representative of the population being
studied, so that some opinions are over- or
underrepresented.
 Sampling error- a polling error that arises on
account of the small size of the sample

for measuring public opinion
 Sample-a small group selected by researchers to
represent the most important characteristics of
an entire population

HOW DOES THIS INFLUENCE POLICY?
Individual doorstep opinions vs. aggregate public
opinion
 Between 1935 and 1979 about 2/3 of all cases
significant changes in public opinion were
followed within one year by policy changes
 Why doesn’t policy always follow opinion

The majority may not be intensely committed as the
minority
 Structure of the government creates a lag time (ex:
supreme court rulings)
