4. Public Opinion
Public opinion is the measure of what the public
thinks about a particular issue, party, or individual
political figure. Historically, it's been pretty difficult to
accurately measure what the public thinks about a
particular issue. However, most forms of democracy
are based on the understanding that the government
will function with the interests of their people in mind.

5. The Shape of Public Opinion
In modern democracy public opinion has a lot of effect on the government.
There are a lot of varieties to produce public opinion views. The main factors
are :
o Social class
o Education
o Region
o Religion
o Age
o Gender
o Race and ethnicity
o Elite and mass opinion

6. Public Opinion Polls
Public opinion polls are designed to measure opinions so
that we can say that the results are reflective of a broader
population.
Many ways exist to measures the public opinion. More
recently, people count the "tweets" of social media to gauge
mass response.
Polling Techniques:
I. Sampling from a population
II. Reaching the sample
III. Asking the questions

7. American Opinion
Presidential Ratings:
 One of the oldest and most important items in U.S. public opinion asks
how the president is handling the job – which is not necessarily how much
people like the president. In practice, however, the respondent who likes
the president will approve of the president's job performance, so the term
"popularity" is often used for this poll.
.

8.  Liberals and Conservatives :
 Political scientists debate whether the divide between liberals and
conservatives is just a flap among elites or whether the American public has
lost its unimodal distribution and become bimodal on ideology.
 Americans are not clear about what they mean by "liberal" or "conservative."
For example, retired people support Social Security and Medicare – the
program of economic liberals – but many call themselves conservatives
because they have traditional values

9. Reliability of Polls
 Public opinion surveys are generally reliable ,provided we recognize their
limits. Overall, the U.S. opinion business takes in several billion dollars a
year, and candidates commission thousands of quick "tracking polls" in
primary and general election.
 Volatility can result if pollsters ask questions that respondents know
nothing about. People want to seem knowledgeable and will give an
opinion to a question ,even if they haven't thought about the issue before.
Pollsters must avoid accidently measuring these non-attitudes. New or
complex issues are the most likely to result in non-attitudes. That's one
reason why public opinion can seem so volatile on those kinds of issues.

10. Pros and Cons of Polling
Pros
 Polls help us understand about the
current mindset of a specific region.
 It is a free publicity for the candidates
that uninterested people can know
about the candidates properly.
 Polls help people know about the
public opinion regarding the
candidates.
Cons
 Critics charge that published or
broadcast poll results can distort an
election.
 Sometimes results in taking voters
away.
 Sometimes effects the contests of the
House, Senate, or state legislatures.

An Election
