Party switching remains a significant career decision in American politics. This study offers the first systematic analysis comparing state legislative switchers and non-switchers across two decades of careers in the American South, where party alignment shifted rapidly toward Republicans.

Data & Methods:

• Analyzed entire political trajectories of all Southern legislators over two election cycles

• Tracked career decisions including reelection chances, retirement patterns, and ambitions for higher office

• Differentiated between converts to GOP versus those who remained Democrats

Key Findings:

• Switching parties comes with predictable short-term electoral costs

• However, former Democrats are more likely than their Republican counterparts to seek higher political positions later in careers • This pattern is especially pronounced during earlier periods when the Republican bench was shallower

Implications:

The results demonstrate that career ambitions significantly influence party-switching decisions despite immediate electoral risks. These findings illuminate how partisan identity evolves and suggest strategic calculations behind legislative career changes.
