Question

How does the two-party system in the United States affect political involvement?

Answer 1

That question isn't right. The U.S. has two major parties, but several more, lesser known, parties. Through the years, people have tended to choose one of the two major parties and stuck with it for all of their life. That seems to have changed in the last 10 years or so.

Answer 2

Most areas tend to lean heavily toward one of the two major parties. That encourages people to feel that their vote doesn't count.
