How can public opinion be expressed?

By voting in elections, the public can express their opinions by choosing a candidate that agrees with their beliefs. Public opinion can also be expressed through writing. Newspaper articles allow people to express their opinions to a wide range of readers. Obviously, the internet is a great way for the public to express their opinions too. With millions of people on the internet everyday, the public's opinion can be easily represented online. Polls are often taken of people to develop a rough idea of what most people agree or disagree with. By participating in these polls, the public is given an opportunity to express their opinions. These are just a few of the ways public opinion can be expressed thanks to the freedom of speech/press given to us by the 1st amendment!
