Polarization in voter media consumption

Fox News splits the parties, and CNN trust is 67% among Democrats versus 23% among Republicans.

In 2025, Democrats' national-news trust was 69%, versus 44% for Republicans; social-media trust was 37% each.

Echo platforms are ideologically homogeneous, retweets reinforce in-groups, and mentions can intensify polarization.

People favor ingroup sources over outgroup sources, especially when affective polarization is high.
