Methodology
Using CrowdTangle, Media Matters compiled a list of 1,773 Facebook pages that frequently posted about U.S. politics from January 1 to August 25, 2020.
For an explanation of how we compiled pages and identified them as right-leaning, left-leaning, or ideologically nonaligned, see the methodology here.
The resulting list consisted of 771 right-leaning pages, 497 ideologically nonaligned pages, and 505 left-leaning pages.
Every day, Media Matters also uses Facebook's CrowdTangle tool and this methodology to identify and share the 10 posts with the most interactions from top political and news-related Facebook pages.
Using CrowdTangle, Media Matters compiled all posts for the pages on this list that were posted on June 24, 2022, and were related to the U.S. Supreme Court’s decision in Dobbs v. Jackson. We reviewed data for these posts, including total interactions (reactions, comments, and shares).
