Obama said in a statement that with its ruling today, the Supreme Court has given a green light to a new stampede of special interest money in our politics. <br/><br/>He said, the court's decision is a major victory for big oil, Wall Street banks, health insurance companies and the other powerful interests that marshal their power every day in Washington to drown out the voices of everyday Americans.
