What term describes a coalition formed between disparate interest groups to support each other's goals?

The term that best describes a coalition formed between disparate interest groups to support each other's goals is logrolling. Logrolling typically refers to the practice where groups agree to support each other's initiatives, often through trade-offs and compromises. This strategy enables different groups, which might have diverse or even conflicting interests, to find common ground in pursuit of specific objectives.

In political contexts, this cooperation is essential for advancing legislation or policies that individual groups might not be able to achieve on their own. By forming coalitions, these interest groups can leverage each other's strengths and resources, thereby increasing their likelihood of success in influencing policies.

The other terms listed do not accurately capture this specific dynamic. Direct lobbying involves engaging directly with lawmakers to influence specific legislation without the collaborative support seen in logrolling. Grassroots mobilization entails rallying the public to advocate for a cause, focusing more on popular support rather than inter-group coalitions. Political action committees (PACs) are designed to raise and distribute funds for election campaigns, rather than facilitating coalitions among interest groups for common legislative goals.
