The book "How Democracies Die" by Steven Levitsky highlights the significant influence of the evolving media environment on political parties, particularly the Republican Party. The author explains that the shift towards more partisan media has resulted in Republican voters increasingly depending on these aligned outlets for news and information. This reliance deepens political polarization and fosters a distinct party identity among Republicans.

In contrast, Democratic voters tend to access a broader range of media sources, which dilutes their party alignment compared to Republicans. The emphasis on partisan media for Republicans contributes to a unique dynamic within the party that reinforces their views and can challenge democratic norms. Levitsky's analysis underscores the crucial role of media in shaping political behavior and its consequences for democratic practices.
