political parties and interest groups differ in which of the following ways.

1. Nature: Political parties are organizations that seek to attain political power by nominating candidates for office and participating in elections. Interest groups, on the other hand, are organizations that aim to influence public policy and decision-making without directly participating in electoral politics.

2. Goals: Political parties usually have broad policy goals and are focused on winning elections to form a government or to influence policy direction. Interest groups are more focused on specific policy issues or sectoral interests and often concentrate their efforts on lobbying and advocating for their particular cause.

3. Membership: Political parties generally have a diverse membership base and attract people who broadly agree with the party's policy positions. Interest groups often have a narrower membership base, usually consisting of individuals or organizations with a direct stake in a particular policy issue.

4. Structure: Political parties typically have a hierarchical structure with a national, regional, and local level of organization, and clear lines of authority. Interest groups can have various organizational structures, ranging from informal networks to more formalized and centrally coordinated bodies.

5. Electoral participation: Political parties contest elections and nominate candidates for public office, while interest groups do not directly run for office. Instead, interest groups try to influence policy outcomes by lobbying elected officials and supporting policies that align with their interests.

6. Scope of activities: Political parties engage in a wide range of activities, including voter mobilization, campaign management, and policymaking. Interest groups primarily focus their efforts on influencing policy agendas, often through lobbying activities, public advocacy, and providing expert input or analysis.

7. Sources of funding: Political parties typically receive funding from membership fees, contributions from individuals and organizations, and public financing, depending on the country's campaign finance regulations. Interest groups usually rely on membership fees, donations, grants, and sometimes government or industry support, depending on their focus and activities.

8. Ideological orientation: Political parties often have a clear ideological orientation and policy platform that guides their actions and positions on various issues. Interest groups can be ideologically driven but are more likely to focus on narrower issues or policy goals, regardless of their ideological underpinnings.
