  In this paper, we provide a quantitative and qualitative analyses of the
viral tweets related to the US presidential election. In our study, we focus on
analyzing the most retweeted 50 tweets for everyday during September and
October 2016. The resulting set is composed 3,050 viral tweets, and they were
retweeted over 20.5 million times. We manually annotated the tweets as
favorable of Trump, Clinton, or neither. Our quantitative study shows that
tweets favoring Trump were usually retweeted more than pro-Clinton tweets, with
the exception of a few days in September and two days in October, especially
the day following the first presidential debate and following the release of
the Access Hollywood tape. On two days in October 2016, pro-Trump tweet volume
accounted for than 90\% of the total tweet volume.
