Beneficial policies can inspire voter gratitude that endures beyond immediate elections.
Context: The 2002 Elbe flooding in Germany created a unique natural disaster scenario to examine policy responses.
We find flood response increased incumbent party vote by 7 percentage points in affected areas during the 2002 election. Notably, 25 percent of this short-term gain persisted into the 2005 election before fading completely by 2009.
This demonstrates that voter gratitude toward beneficial policies can have a longer-lasting effect than previously assumed. The findings offer important implications for understanding democratic accountability mechanisms and evaluating public policy effectiveness.
💡 Key Insights:
• Natural disasters create opportunities to study long-term electoral consequences of crisis responses
• Incumbent parties receive significant credit following disaster-related policy interventions
• Voter gratitude appears durable but eventually fades as memories recede
