U.S. Senatorial Approval and Ideological Extremism Replication Data

Replication package for a study on ideological extremism and senatorial approval in the United States. The data includes processed Cooperative Election Study (CES) files and Voteview member data. A master script builds the analysis dataset and reproduces all tables and figures from the associated paper.

Use Cases

• Replicate regression analyses on senatorial approval based on ideological extremism scores.
• Reproduce figures illustrating the relationship between uniform punishment, conditional reward, and approval.
• Analyze processed survey data from the Cooperative Election Study (CES) for political behavior research.
• Examine the alignment between member ideology data from Voteview and public approval metrics.

Strengths

• Includes the exact processed data files used to generate all results in the published paper.
• Provides a master script (`master.do`) to fully reproduce the analysis from raw inputs.
• Combines two established data sources: Cooperative Election Study (CES) and Voteview member data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
