Party alignment significantly impacts legislative behavior, as members of political parties often vote according to shared ideologies and platforms. When members are aligned, there is typically greater cohesion in determining policy directions, resulting in either efficient governance or heightened partisanship. Majority parties can prioritize their agendas through majority rule in committees and floor votes, which often diminishes bipartisan collaboration. Consequently, party alignment can shape critical issues, such as budget, healthcare, and immigration policies, affecting public perception of governance.
