I've always wondered what consisted in the path to presidency, I do know that it starts with the nomination phase. Moreover, I've found that there is an initial invisible primary and a Declaration of candidacy as well. For nomination however, there needs to be conversion from local caucuses to the eventual national conventions. For instance the Iowa Caucus is very important.
For the primary elections there can be both open and closed. Open primaries consist of independents getting whatever ballot they wish for, and Closed primaries consist of only registered party members and this occurs more often. The national convention chooses a "presidential nominee" before hand and this transcends to the development of a party platform.
Now the campaign phase of the election takes part. Until election day both parties campaign directly against each other. For instance for the latest election there were 3 public debates between Hilary Clinton and Donald Trump. There usually is one vice president debate as well. In this phase there are many TV Commercials, radio ads, and many other social media aspects. Moreover, these are usually held in strategic areas where the moderators and candidates agree on.
The general election day usually falls on the first Tuesday after the first Monday of the month of November. Elections are 2 part: there's a popular vote and electoral vote. For each state the number of electoral votes is proportionate to the number of senators and representatives in the state. The votes will be counted after the Electoral College takes an oath .
The electoral college is the compromise between the people who want a direct election and the individuals who want Congress to elect a president. There's a total of 538 electoral votes, and California has the highest with 55. The candidate with the most wins in all the state's electoral votes win.
Lastly, at January 20th 2017 at noon the president is officially sworn into office by taking the Constitutional Presidential Oath to serve and defend and carry out all constitutional duties given to them by the chief justice of U.S. Supreme Court on the steps of the capital. Gosh! After all this research I'm able to understand the path to presidency.
