Most of his legacy is an unmitigated disaster: Viet Nam, the War on Poverty, the much overlooked budget unification act -- when the Social Security budget was consolidated with the government operating budget, so that we could "afford" both a War in Viet Nam and a War on Poverty. All illustrate the utter failure of "good intentions".
Meanwhile, all the positive parts of his legacy (the Civil Rights Act, e.g.) were fostered by cynical, self-serving political calculation -- i.e., "bad intentions".
As a nation, and on balance, we would be better off without LBJ and his dubious works.
It's striking but not surprising that Johnson wanted to maintain his Senate leadership position as Vice President. One would have thought that LBJ would rig things so as to keep the power and exercise it behind the scenes after he left the Senate. But I guess he wasn't quite as clever as he liked to think himself.
But really, starting the list of his offenses with public urination is hardly fair. For those were different times with different manners, indeed. Another review (continued here} has a more entertaining -- or repellent -- story about Johnson's, er ... Johnson, whom he apparently called "Jumbo."
If Richard M. Nixon had REALLY wanted to be a crook, he would have paid Lyndon Johnson to teach him how!
