What role did third-party candidates play in the 2016 election and how did their presence impact the overall outcome?

Third-party candidates, such as Gary Johnson and Jill Stein, played a minor role in the 2016 election by attracting some voters who were dissatisfied with the major party candidates. However, their presence did not significantly impact the overall outcome as neither candidate won any electoral votes and did not sway the election in any particular direction.
