Data & Methods: Using data on recent presidents' administration and congressional interactions, combined with quantitative analysis methods including regression models.

Key Findings: Results demonstrate systematic bias toward allocating grants to copartisan senators despite mixed evidence regarding strategic effectiveness or electoral benefit. The findings highlight a persistent pattern of preferential treatment that transcends typical political considerations.

Implications for Political Science Research: This research contributes significantly to understanding the dynamics between executive and legislative branches, particularly concerning resource allocation politics within party structures. It offers new insights into pork-barrel spending patterns and strategic representation behaviors.
