This study challenges common assumptions about political parties in multiparty democracies by examining how issue engagement differs across Members of Parliament (MPs) rather than treating them as unified entities. We explore two key dynamics: intraparty division of labor, where specialized policy experts focus on specific issues within their party, and the distinct communication style of party front benchers who prioritize interactions with other party leaders when addressing topics.

Our analysis employs spatial lag models using approximately 15,000 press releases authored by Austrian MPs. The findings provide empirical support for these distinct patterns in issue engagement.

What This Means:

The "unitary actor" framework used to study political parties is insufficient for understanding how issues are addressed across different legislative bodies and roles within them. Understanding this complexity offers crucial insights into the mechanics of legislative communication.
