Political Parties are by Definition Unethical

Political representatives are elected to represent the interests of their constituency in government. Political parties pay to get people with similar views elected to government. Although these interests may often coincide; when they do not, the party will always pressure the representative to act counter to the interests of their constituency and instead act in the self interest of the party. Thus every representative will inevitably be asked by their party to violate the ethics of the job they were elected to do.
