That was more because of the things he did pass (such as the Smoot-Hawley Tariff Act), not the things he vetoed.
Interestingly enough, the Democratic Party platform of 1932, which candidate Roosevelt endorsed, called for a 25% reduction in taxes and spending. That (at least in part) is how Hoover got defeated.
No question, Hoover was responsible for too much Gov't intervention during the Great Depression.
Roosevelt did run to his 'right' during the campaign, which should have been a lesson to Republican voters about trusting Democratic rhetoric (like JFK, Carter and Clinton)
The point is that spending bills are the responsiblity of the Congress, not the White House.
That is how the Constitution was written.
