You are absolutely correct. Many of the remedies for the depression which were enacted by FDR were originally proposed by Hoover, but he was blocked by Dumocrats for purely political reasons (sound familiar?). They wanted a Dumocrat President, which of course they got.
In the 71st Congress(1929-1931) there were 56 Republican Senators, 39 Democrat Senators, 1 DFL. In the House there were 270 Republican Congressmen to 164 Democrats. In the 72nd Congress (1921-1933) there were still 48 Republican Senators to 47 Democrats and 1 DFL. And in the House there were 218 Republicans to 216 Democrats. So Hoover had Republican majorities throughout his term. What exactly did the Democrats block and how did they block it?
Disagree. The Democrats gave Hoover pretty much everything he wanted including the RFC and his bone-crushign income tax increase. It is true, however, that FDR refused to cooperate with Hoover's recommendation for a bank holiday and other measures. FDR wanted the glory.
