Independent Vermont Senator Bernie Sanders is warning Americans that two ultra-conservative billionaire brothers will soon hold more political power than both the Democratic and Republican Parties. While speaking to a group of supporters in Iowa last week, Sanders explained why he was considering a run for the president of the United States in 2016. "It is likely in a very short period of time that the Koch brothers themselves will have a stronger political presence than either the Democratic or the Republican Party," the lawmaker noted.
