Most states have primary elections to decide which candidates will be on the Novembergeneral election ballot. Some states parties hold conventions in conjunction with theprimary. If a candidate is unopposed, there may not be a primary election. Those whorepresent a major political party are automatically placed on a state's primary ballot.Minor party candidates are chosen by their party's rules while independent candidatesnominate themselves. Independent candidates and those representing minor parties must meetvarious state requirements to be placed on the general election ballot. An example of thiswould be to submit a petition with a certain number of registered voters.
Senate and Representative elections differ in who votes for the candidates. Alleligible voters within a state may vote for Senator. A Representative is elected by onlythose eligible voters residing in the congressional district that the candidate willrepresent. Election winners are decided by the plurality rule. That is, the person whoreceives the highest number of votes wins. This may not necessarily be a majority of thevotes.
