Update: Aug. 9, 2014
CNN finally reaired this episode Saturday Aug 9 at 1 AM EDT and I recorded it.
One of the highlights is LBJ's speech on March 31, 1968 when he ways he will not run again. "A House Divided Against Itself Cannot Stand". I was on KP in Special Training Company at Fort Jackson, SC in Army Basic Combat Training at the time.
The assassination of RFK is shown (it wasn't apparent at first it had happened).
The 1968 Democratic Convention in Chicago is shown as being conducted in "a police state".
The country was coming apart, over the generation gap.
