This difference is rooted in the idea that unlike political parties, interest groups have no interest in ruling states or countries. Another difference is group organization. Political parties are normally well-knit and organized. Including a proper constitution. It’s their way to explain why they are together, the functions of their particular party, and the titles and roles of the members. They are also very flexible in their stance on issues, easily switching positions. This is probably why political parties seemingly work much more in unison than interest groups. Interest groups are somewhat loosely organized. They are usually just working to achieve a common goal or goals. This means that they do not necessarily need a constitution for them to do their work. Because of this, the internal politics of interest groups are less flexible, they cannot change their stance without changing who they are.
