Final answer:
Most interest groups in the United States are not nonpartisan.
Step-by-step explanation:
In the United States, the statement that most interest groups are nonpartisan is false. While many interest groups claim to be nonpartisan, there are numerous examples of interest groups that have strong affiliations with either the Democratic or Republican Party. For instance, the American Conservative Union, Citizens United, the National Rifle Association, and National Right to Life are more likely to have relationships with Republican lawmakers than with Democratic ones, while groups like Americans for Democratic Action and People for the American Way have stronger relationships with the Democratic Party.
