Step-by-step explanation:
Political parties have a significant impact on public policy by working to get individuals who promote party ideology elected to Congress. This means that the statement Political parties help get individuals who promote party ideology elected to Congress is true.
Political parties recruit candidates who align with their party platform, and when these candidates are elected, they work together to enact legislation that reflects the party's values and goals.
