That would depend on your definition of "liberal" Assuming all Democrats to be liberal, FDR and LBJ were very successful. FDR changed the nature of American government by making it a resource for individual Americans with Social Security and collective bargaining legislation. LBJ furthered that wih Medicare and civil rights.
Social Security was a ponzi scheme to collect money and spend it on other liberal causes and guess what, that's what happened. It's true LBJ passed the civil rights legislation thankfully with mostly Republican support. The Democrat Party.. not sooo much.
BTW...They were both filthy rich and war Presidents..isn't that a huge problem for Democrats?
