No. Governor Connally led the charge that ousted LBJ's best ideological friend, "progessive" Senator Ralph Yarborough. It was with Connally's help that Lloyd Bentsen was able to run as a Conservative Democrat in order to beat the died-in-the-wool communist Yarborough.
Thus, the Left's 2 greatest **Democratic Party** enemies were in that same car together in Texas that day: Connally and Kennedy.
Within a few more years, 3 other right-wing Democrats were attacked (House and Senate) via "muggings" and plane crashes, and surviving right-wing Democrats "found religion" by shifting Left.
The end result was that the Democratic Party lost all of its right-wing power-players. What remained in the smoky backroom halls of Democratic Party power were leftists.
....sooooo what your saying is it was people in the democratic party that did this?......
Who were the other three. Scoop Jackson was a anti-Commie dem back then. Was he one?
