On Tuesday, Jan. 21 at 7 p.m., both the Democrats and Republicans in Iowa will have Precinct Caucuses. The Caucus is the building block of the party. It is an opportunity for citizens who haven't yet been involved in a party to get involved. The people who attend the Caucus help mold the tenor of the party. If a lot of right-wingers or left-wingers attend the caucuses, the party can become more extreme. If more people attend who are interested in a particular topic, that can also affect the direction the party goes. If you don't go to the caucus to help start the party process, you will miss out on one chance to influence the direction of the conversation in this country.
