This report provides answers to frequently asked questions about the presidential nominating process, including how the delegates to the national conventions are chosen, the differences between a caucus and a primary, national party rules changes for 2012, and the national conventions themselves. It is not a comprehensive report on all aspects of the presidential nominating process. The Nominating Process The presidential nominating process is a subject of enduring congressional and national interest. Presidential elections are the only national elections held in the United States, and the initial phase of primaries and caucuses changes every four years. Congress has a legislative, as well as a practical and political, interest in the presidential nominating process. Presidential nominees lead the party ticket in the fall election; the elected president will set many policy and political goals in the ensuing four years; and many Members of Congress will serve as delegates to the major party conventions. No legislation has been introduced in the 112th Congress to reform the presidential nominating process, although several related bills would eliminate taxpayer financing of the national party conventions, including H.R. 359, H.R. 414, H.R. 3463, and S. 194.
