  The global proliferation of social media platforms has transformed political
communication, making the study of online interactions between politicians and
voters crucial for understanding contemporary political discourse. In this
work, we examine the dynamics of political messaging and voter behavior on
Twitter during the 2022 Italian general elections. Specifically, we focus on
voters who changed their political preferences over time (swing voters),
identifying significant patterns of migration and susceptibility to propaganda
messages. Our analysis reveals that during election periods, the popularity of
politicians increases, and there is a notable variation in the use of
persuasive language techniques, including doubt, loaded language, appeals to
values, and slogans. Swing voters are more vulnerable to these propaganda
techniques compared to non-swing voters, with differences in vulnerability
patterns across various types of political shifts. These findings highlight the
nuanced impact of social media on political opinion in Italy.
