The American presidential election is a very dramatic media event. In the era before the rule of mainstream media, information acquisition basically depended on mainstream media. The emergence of television and Internet, especially social media, has intensified the trend of media and drama in American politics.

Social media has become an unprecedented way of political participation and mobilization, helping outsiders break through various filters and obstacles and enter the political center. In addition to expanding the spread of the US presidential election, social media has gradually become a new "battleground for military strategists" in the election. How to use social media to publicize party politics and win votes has become a new problem faced by candidates, which reflects not only the changes in the propaganda platform, but also the changes in the propaganda thinking of the candidate team.

Trump entered the White House, and the US election has also come to an end. Looking back at the scuffle between Trump and Hillary, social media actually played a great role and even occupied a crucial position. Trump is very good at using social media. During the general election, more than half of the hot words were caused by Terplan. Trump's support rate on social media is much higher than Hillary. Although these data can't directly determine the final election result, they also indirectly lubricate and promote Trump's victory.

The dust has settled in the US election. Looking back on this election, social media will undoubtedly add a lot of color to the entire American election process. Although it can't be said that social media played a leading role in the election, it will play an increasingly important role in the future American election.
