  Popularity is a critical success factor for a politician and her/his party to
win in elections and implement their plans. Finding the reasons behind the
popularity can provide a stable political movement. This research attempts to
measure popularity in Twitter using a mixed method. In recent years, Twitter
data has provided an excellent opportunity for exploring public opinions by
analyzing a large number of tweets. This study has collected and examined 4.5

This research has benefits for politicians, informatics experts, and
