  The study involved the analysis of emotion-associated language in the UK
Conservative and Labour party general election manifestos between 2000 to 2019.
While previous research have shown a general correlation between ideological
positioning and overlap of public policies, there are still conflicting results
in matters of sentiments in such manifestos. Using new data, we present how
valence level can be swayed by party status within government with incumbent
parties presenting a higher frequency in positive emotion-associated words
while negative emotion-associated words are more prevalent in opposition
parties. We also demonstrate that parties with ideological similitude use
positive language prominently further adding to the literature on the
relationship between sentiments and party status.
