Polarization Shields Incumbents: Economic Voting Falls When Parties Drift Apart

Why This Question Matters

Electoral accountability depends on voters blaming incumbents for bad outcomes. Thiago de Miranda Queiroz Moreira asks whether rising political polarization undermines that accountability by changing how voters punish incumbents for poor economic performance.

What the Author Tests

The paper focuses on two concrete sanctioning channels: voting for the opposition and abstaining from the vote. The central claim is that as ideological distance between parties increases, fewer voters use either channel to punish incumbent parties for negative economic conditions.

Evidence and Methods

• Analyses of county-level presidential election results examine how electoral responses to weak economies vary across levels of political polarization.
• Complementary survey analyses probe the psychological mechanisms: respondents' perceived ideological distance between parties and how that affects economic evaluations and willingness to punish a co-partisan incumbent.

Key Findings

• In more polarized environments, the number of voters who punish incumbents for poor economic performance falls for both pathways: switching to the opposition and abstaining.
• Survey evidence shows two linked mechanisms: as perceived ideological distance grows, partisans are (a) less likely to report negative evaluations of the economy when their party holds the presidency, and (b) even among respondents who do view the economy negatively, partisans are less willing to translate that view into punishment of their party.

Why It Matters for Voting and Elections Research

These results indicate that polarization can blunt the informational and sanctioning role of elections by altering both economic perception and the translation of perception into electoral behavior. The findings have implications for theories of retrospective voting, partisan bias in political evaluation, and the capacity of democratic elections to hold leaders accountable in highly polarized contexts.
