The Interregional Primary Plan is a proposed reform to the United States primary calendar supported by Representative Sandy Levin and Senator Bill Nelson, both Democrats. The plan would break the country into six regions. From those regions, one subregion - either a single state or a group of smaller states - would vote on each primary date (e.g., all A states,) with the entire country having held its primaries after the sixth set of primaries votes. Each state would vote first once every twenty-four years, with the first set of primaries determined by lottery and cycled thereafter.[1]
Historically, the presidential primary season started slowly, ramping up several weeks after the Iowa caucuses and the New Hampshire primary. In the 2008 Presidential primary season, with competition to increase the relevance of each state's selection process, 34 states (plus the District of Columbia), have scheduled their primary or caucus process to be held in January and February, tripling the number of states voting this early than the count in the 2000 races.[2]
