This is only a problem because there is no one to represent the minorities and the poor. Also, people and corporations that make the largest donations to campaigns do not share the same views with the general population. The wealthy are living very different from the poor, such as opposing estate tax, which would hurt the few wealthy. Politicians will listen to those who give them money so that they can depend on that money being there again when it is time for reelection. Sequentially, the powerful people that donate money to the election funds need to be refunded for their donations, which are why so much legislation, such as taxes targets the non-wealthy. If the legislators target the wealthy, they will not receive campaign contributions from them, so they lose either way. Which makes the poor stay poor, and the wealthy stay wealthy.
Campaign Financing is out of control in today's political races. Candidates are taking money from wherever and whomever they can get it. So-called "Soft money" is flowing through elections without care or caution. People who make these contributions do not share the views of the average citizen, so politicians end up representing the wrong people or just a select few. Money decides races, sometimes leaving the better man but lighter spender out of an arrangement. Candidates make decisions based on what will help them financially then what is better for the people. Contributions by industry are made not in the interest of the people, sometimes hurting them in ways they don"t even know. No matter what the opposition might possibly say campaign finance reform is needed urgently to keep our democracy as our founders intended it.
Individual donors making a $200 dollar or more contribution to a campaign fund make up only .33% of the population. These extremely small percentages of mostly wealthy individuals gain the power to influence politicians to their liking.
