An election is a process, i.e. an organized event in which people go out and elect a person for a political office or other position by voting. For example, we have the presidential election, typically occurring once every four years, since the president has a 4 year term. An example would be the 2016 US election, an election where Donald Trump was named the 45th president of the US.
