Traitor to His Class -- The Privileged Life and Radical Presidency of Franklin Delano Roosevelt, by H. W. Brands. It is wonderful! And it proves quite nicely that Republicans haven't changed in at least 80 years.
Chapter 19, page 238, Roosevelt begins to explain his view of the presidency ...
Roosevelt proceeded to explain what his candidacy entailed. In radio addresses and in person he spoke, as he put it, on behalf of the "forgotten man at the bottom of the economic pyramid." For too long, he said, government had operated for the benefit of the wealthy, consigning the poor to the margins of public life. The Hoover administration had responded to the crisis by furnishing aid to big banks and corporations. This approach was characteristic of the Republicans, Roosevelt said, and characteristically wrong. It treated ordinary men and women as secondary to the powerful firms that had long dominated American life. And it certainly hadn't done anything to alleviate the depression, which grew worse with each passing month. Roosevelt advocated "building from the bottom up," as he put it: supplying aid to those who most needed it.
