Political satire is satire that specializes in gaining entertainment from politics; it has also been used with subversive intent where political speech and dissent are forbidden by a regime, as a method of advancing political arguments where such arguments are expressly forbidden.
Political satire is usually distinguished from political protest or political dissent, as it does not necessarily carry an agenda nor seek to influence the political process. While occasionally it may, it more commonly aims simply to provide entertainment. By its very nature, it rarely offers a constructive view in itself; when it is used as part of protest or dissent, it tends to simply establish the error of matters rather than provide solutions.
