Final answer:
Strong party discipline combats the lack of party unity among legislators.
Step-by-step explanation:
The lack of party unity among legislators can be combated by strong party discipline. Party discipline refers to the ability of a political party to enforce unity among its members and ensure that they vote in line with party policies and decisions.
Strong party discipline helps to prevent individual legislators from deviating from the party line and promotes a sense of cohesion within the party. It allows the party to present a united front and increases the likelihood of legislative success.
For example, the party leadership can use rewards and punishments, such as committee appointments and campaign funding, to incentivize party members to vote together. By enforcing party discipline, legislators are more likely to prioritize party unity and work together towards common goals.
