<human>:  What is the history of the race for presidency in the United States?
<bot>: The history of the race for presidency in the United States dates back to 1787 when the Constitution was ratified, setting up the framework for the election of a president. The election of George Washington in 1789 is seen as the first successful presidential election in US history and from then on, presidential elections have taken place every four years. Each election has seen a new candidate come forward as the country's choice to lead the nation. Over time, the race for presidency has grown increasingly competitive, pitting candidates from different parties against each other. Today, the nomination process and electoral college system, as well as the influence of third-party candidates, all play an important role in determining the outcome of the general election.
