When faced with co-partisan politicians who disagree publicly, what side do partisan voters take? We draw on social identity theory to develop a theory of partisan leadership cues arguing that leaders have a key role in social groups and because of that centrality, and accounting for affectbased motivation, co-partisan voters resist ingroup dissent. We test this theory with a series of experiments focused on leaders who violate democratic norms and responses from within the party that reflect loyalty or dissent. Our findings show that co-partisan voters are loathe to punish misbehaving leaders, except when their action represents a major threat and the criticism comes from a high ranking party member. Ingroup critics of the leader risk their own reputation in the process. Importantly, these effects go beyond motivated reasoning: leadership effects occur even in fictitious partisan contexts when partisans have no prior affect for a leader or critic. Our findings point to the power of party leaders in groups and raise questions about the prospects for democratic criticism and accountability.
