Final answer:
Political parties must manage tensions and conflicts within their coalitions to achieve electoral and policy success.
Step-by-step explanation:
Political parties in the United States must manage tensions and internal conflicts to hold their coalitions together for electoral and policy success.
Parties face disagreements and conflicts over major policy priorities, as they need to balance broad appeal with the interests of their diverse coalition members. For example, if a party takes too narrow a position on issues, it may marginalize itself, but if it takes too broad a position, internal disagreements may arise.
Furthermore, parties can experience divisions within their ranks. Party leaders may face challenges from factions within their parties that have different ideologies, priorities, or strategies. Internal conflicts can weaken the party's ability to pass legislation and achieve electoral success.
