What voting style involves a legislator voting in line with their political party?

The voting style where a legislator votes in alignment with their political party is known as partisan voting. Partisan legislators prioritize the interests and policies of their party over personal beliefs or constituents' preferences. This approach reflects a commitment to party unity and often aims to advance a collective agenda or uphold party principles. When legislators vote as partisans, they contribute to the overall strategy of their party, which can influence major legislation and party positioning on various issues.

In contrast, the delegate model implies that legislators act strictly according to the wishes and interests of their constituents, while the trustee model suggests that they make independent decisions based on their judgment. The politico approach combines elements of both delegate and trustee models, allowing legislators to switch between the two styles based on the specific situation or issue at hand. However, in partisan voting, the alignment with party is the defining characteristic.
