Final answer:
Political parties influence how the constitution is interpreted by organizing Congress along party lines, aligning issues important to voters, and creating party platforms.
Step-by-step explanation:
One way political parties influence how the constitution is interpreted is by organizing Congress along party lines. They do this by aligning sets of issues that are important to voters and presenting them in documents known as a party platform. This helps guide members of Congress in drafting legislation and informs party members how they should vote on important issues. Additionally, political parties nominate candidates to run for state government, Congress, and the presidency, allowing them to shape the government and its processes.
