And now let me tell you something that no other candidate for president will tell you. And that is no matter who is elected to be president, that person will not be able to address the enormous problems facing the working families of our country. They will not be able to succeed because the power of corporate America, the power of Wall Street, the power of campaign donors, is so great that no president alone can stand up to them. That is the truth. People may be uncomfortable about hearing it, but that is the reality.
-- Bernie Sanders, Clear Lake, Iowa, 14 August 2015
