"Party discipline" refers to the ability of a political party to ensure that its members consistently vote in alignment with the party's official positions or directives. This cohesiveness is vital for maintaining control over legislative processes and achieving political objectives. Effective party discipline can lead to a unified front on key issues, facilitating the passage of legislation. Conversely, a lack of discipline may result in fragmentation within the party, undermining its effectiveness and compromising its bargaining power within government.
