WTF? LBJ was THE REASON the civil rights legislation passed (yes, Hubert Humphrey was the centerpiece, but it could not have passed without LBJ's strong support). He passed Medicare and Medicaid. Yes, Viet Nam was a huge disaster, but that is also the case for Nixon I who you list sixth! And Nixon was literally the closest president who threatened liberal democracy before Trump and most of his serious crimes (break ins, briberies, attempted criminal frames) occurred during his first term. FFS.
