So who's part of the 29%?

I think it's fair to say FDR is viewed more favorably for what he inspired us to do, more than what he did himself policy-wise. In other words, he showed leadership in a time of crisis, and that is what most Americans want from their political leaders.

I don't think it's fair to say that. FDR's policy for intervention in Europe wasn't popular but proved to be his greatest legacy. After WW1 the population had become isolationist (and who could blame them). At Churchill's urging FDR finally realized that the US would have to engage in order to defend the Western way of life. FDR was slowly pushing the country in that direction and Pearl Harbor came along and that made it easier for him to pull the trigger.

Sure the dude was inspiring, but he also had some pretty policies.
