Presidential election primary and caucuses are two very different methods of accomplishing the same basic matter . just put , they are both a means for each political party to let vote­rs nationwide select their political party ’s presidential nominee . More specifically , primaries and caucus are substance of selectingdelegates(representatives of party members in each province ) to send to the party’snational convention .

­ At each company ’s internal convention ( held the summertime before the presidential election ) , the political party selects a presidential nominee based on how company delegate at the conventionalism vote . The Republican and Democratic parties in each state select delegates based on either caucuses or a primary vote in that state – the delegates are sent to represent voters in the nation .

­At the popular convention , the routine of state delegates is proportional to the number of right to vote received in the state primary winding or caucus . The Republican Party allow states to practice either a achiever - take - all system ( where the delegate or candidate with the most votes in a state ’s elemental or caucus wins the right field to be represented by all of the company ’s delegate at the national convention ) , or a proportional system . ( States that hold former primary coil must use a proportional allocation.)[source : GOP ] .

The total number of delegate each party can send to the national convention is again dictate by political party rules . commonly the party determines the telephone number of delegate through a formula factoring in state population , the act of elected official in place , and that state ’s past support of party candidates .

Union law does n’t order how country choose their delegates , so individual states resolve what system to habituate . Most states habituate the primary organization – where voter statewide simply cast a voter turnout for the candidate they support – but some use the elder caucus system .

The term caucus ostensibly comes from an Algonquin word meaning " assembly of tribal chieftain , " and the principal Southern Cross of the caucus system today is indeed a series of meetings . To see how this works , let ’s look at the Iowa caucus – the first " voting event " of the presidential election year .

The Iowa Caucus

In Iowa , the caucus themselves are local party precinct meeting where registered Republicans and Democrats conglomerate , hash out the candidates and vote for their campaigner of selection for their party ’s nominating address ( Iowa caucuses actually occur every two years – in non - presidential - election years , participant more often than not discourse party political platform issues ) . In both party , the intent of the caucus vote is to select delegate to attend a county convention – each caucus sends a certain number of delegate , based on the population it represent . The delegates at the county convention in turn blue-ribbon delegate to go to the congressional district nation convening , and those delegate choose the delegates that go to the interior convention .

The Republican caucus voting system in Iowa is relatively straightforward : You come in , you vote , typically through secret ballot , and the percentage of the radical supporting each candidate decide what delegates will go on to the county convention .

The Democrats have a more complex system – in fact , it ’s one of the most complex pieces of the entire presidential election . In a typical caucus , registered Democrats tuck at the precinct meeting places ( there are around 1,700 precinct statewide ) , champion for each nominee have a probability to make their case , and then the participants forgather into groups supporting particular campaigner ( undecided voter also cluster into a mathematical group ) . In order for a particular radical to be executable , they must have a sure percentage of all the caucus participants . So participants will endeavor to convert their neighbor to join their grouping . If they do n’t get enough people , the group disbands , and its penis go to another group . The pct cut - off is determined by the bit of delegate portion to the precinct . It break down like this :

If the precinct has only one delegate , the group with the most masses wins the delegate right to vote , and that ’s it .

Once the groups are settled , the next order of business is to figure out how many of that precinct ’s delegate each radical ( and by extension , each candidate ) should win . Here ’s the rule :

­For example , say a precinct has four delegates , 200 caucus participant , and 100 masses support John Doe . To figure out how many delegates you assign to John Doe , you would multiply 100 by four , to get 400 . You divide 400 by 200 and get 2 . So John Doe gets two of the four delegates .

The media reports the " success , " establish on the pct of delegates going to each campaigner . This is n’t on the nose accurate , since it ’s actually the state convention that resolve what delegate go to the home convention , but more often than not , there ’s a clean statewide winner after the caucuses .

The convoluted caucus organization dates back to 1796 , when American political party go forth , and it has n’t changed a whole batch since then . Most land eventually replaced this organization , because as political party became more centralized and advanced in the early 20th century , company leaders or " boss " were perceive as exerting too much control over take a candidate . To give item-by-item voters more influence over the nomination process , political party leaders create the presidential principal system . Florida held the first primary in 1901 commemorate the outset of the presidential primary we know today .

Dramatic caucus reforms and rule that the Democratic Party instituted at the state level in the 1970s change the system significantly . plan to improve and open up caucus to all party members , the requirement in reality made caucuses more hard to manage and unknowingly led to the rise of primaries . To help State coordinate the election days of both party , the Republicans also switch their system .
