Assignment 2: It May Not Work in Politics
Write a three page paper in which the student addresses the
following three (3) items using headers to separate each
response:
1. Congressional Ethics. Identify one (1) member of Congress
who has been charged with ethics violations. Briefly discuss the
reason for the charges and provide two (2) reasons why you
agree or disagree with the verdict and any penalties. Provide
examples to support your answer. Note: Consider how the
verdict and penalties impacts your trust of the members of
Congress.
2. Third Party Candidates. Discuss two (2) political reasons
why a third party candidate has never been successful in
winning a presidential election. Provide examples to support the
answer. Note: Consider the political impact of the Republican
and Democratic Party if a third party was successful.
3. Federal and State Authority. Identify one (1) current issue
facing the United States today. Analyze the respective roles of
Federal and state authorities in addressing the issue. Determine
whether the U. S. Constitution constrains the Federal and state
responses to the issue. Explain.
