Here are some of LBJ's dubious "achievements":

Changed the accounting on the Federal budget, so that deficts are concealed until after they're spent
Stacked the courts with leftist judges
Of course, the Great Society
LBJ has been out of office for 40 years, and we still feel the impact of his errors.
