Summarize the ways in which various campaign finance laws have restricted the political activities of groups, including corporations and unions

The federal laws claim strict disclosure of different requirements and donations that limits and impinge privacy rights, freedom to express and hampering the political participation process. However, according to the opponents, the "federal campaign laws" do not go far to "mitigate corruption" and unnecessary influence of interests that are not disclosed.

It should, however, be noted that the federal laws are applicable for people who took part in the elections. This is because it is the state that enacts and enforces the laws for local elections.
