reach the largest number of potential voters. This tactic does have its drawback however as it is the most expensive form of advertisement. Even though it reaches the largest number of potential voters it is not the most effective way of swaying voters. The most effective way is believed to be through personal contact as many political scientists agree. It is confirmed that it is much more effective than contacting potential voters by email or by phone, (Sides et al., pg. 147 para, 2, 3). These are just some of the wide variety of tactics used in campaigns. The popular vote on Election Day Under the United States Constitution, the manner of choosing electors for the Electoral College is determined by each state's legislature. Although each state designates electors by popular vote, other methods are allowed. For instance, instead of having a popular vote, a number of states used to select presidential electors by a direct vote of the state legislature itself. However, federal law does specify that all electors must be selected on the same day, which is "the Tuesday next after the first Monday in November," i.e., a Tuesday no earlier than November2 and no later than November8. Today, the states and the District of Columbia each conduct their own popular elections on Election Day to help determine their respective slate of electors. Generally, voters are required to vote on a ballot where they select the candidate of their choice. The presidential ballot is a vote "for the electors of a candidate" meaning the voter is not voting for the candidate, but endorsing a slate of electors pledged to vote for a specific presidential and vice presidential candidate. Many voting ballots allow a voter to "blanket vote" for all candidates in a particular political party or to select individual candidates on a line by line voting system. Which candidates appear on the voting ticket is determined through a legal process known as ballot access. Usually, the size of the candidate's political party and the results of the major nomination conventions determine who is pre-listed on the presidential ballot. Thus, the presidential election ticket will not list every candidate running for president, but only those who have secured a major party nomination or whose size of their political party warrants having been formally listed. Laws allow other candidates pre-listed on a ticket, provided enough voters have endorsed that candidate,
