Chapter 7 tests the four mechanisms of socialization derived from the qualitative data formally with original survey data from Cameroon. The analysis shows that, first, people raised in partisan households are much more likely to adopt partisan identities later in life than people raised in apolitical households. Second, party militants are more politically influential in their social networks than regular partisans or nonpartisans. Third, the partisan homogeneity of contemporary social networks is highly predictive of individual partisanship. Finally, because of the nature of politics in electoral autocracies, opposition partisans face higher levels of cross-partisan influence than ruling party partisans.
