Because of the Citizens United ruling by the Supreme Court of the United States, money is speech. Therefore the more money you have, the more speech you have, and the more speech you have the more loudly your voice is heard. The more money you have, the more political influence you have. Because of the Citizens United decision, the politicians are no longer beholden to the will of the voters, but to the will of the donors. The Supreme Court is not supposed to make law, that is the providence of the Congress, but here they made law. Money is speech and corporations are people. If you can't match their donations, you shut sit down and shut the fuck up because you do not count anymore with your pithy vote an no money to donate.
