There are other political parties out there, such as the Green Party, Libertarian, Constitution Party. The problem is the alternative parties do not recieve any of the attention of the media and therefore are not well known. In this politcal arena, money talks. Corporations are considered "persons" under the law and therefore have their rights protected by the law. Financial contributions are considered a form of speech. That of course means that multi billion dollar corporations can contribute massive amounts of money to any political party it chooses. It is doubtful that they would back a prty that has the interests of the general population. They of course are going to do everything they can to protect their profit margin.
