Answer:
Violate a person's First Amendment rights.
Step-by-step explanation:
When someone wishes to limit donations in relation to the money spent on the policy, that person violates the rights defended in the donor's first amendment. This is because when someone decides to make this type of donation, it means that that person is exercising their right of free association, in addition to being able to make a peaceful petition to the government, which are rights defended in the first amendment.
In other words, critics of the restrictions on the amount of money spent on politics argue that limiting donations would violate a person's first amendment rights.
