The worst President in history was Obama, economically speaking. But because the US was already bouncing on the bottom, and Trump was unable to do much about it with mostly a Democrat Congress (remember that the President proposes a budget. Congress often passes something unrecognizable in response - especially the opposition) Brandon may not eclipse Obama as the lowest growth administration in history. But his other misbehaviors are certainly earning him a unique place in history previously reserved for dullards like Taft.

Nothing new.
