Who had the most to gain?
LBJ.
Yep..., he was going to get dropped from the Kennedy ticket — and — he was going to end up going to jail for along time on the Billie Sol Estes scandal...
In a “real world sense” — LBJ had the most to gain and it makes the most sense...
ALSO..., there is a connection with LBJ, the Billie Sol Estes scandal — and — the *second stand-in* for Oswald (the one the CIA used as “cover” for the real Lee Harvey Oswald, the one that fooled the Soviet Union with Lee Harvey Oswald being the CIA double-agent, to spy from inside the Soviet Union, which is why Oswald came back to the U.S.).
This “second” was part of the group that worked with LBJ and Billie Sol Estes. They probably used Oswald as a convenient patsy.
And that was why Oswald was a “cool cucumber” in the interrogation at the Dallas Police, because he knew that the information would come out that would clear him. And that’s why those guys had to get Ruby to kill Oswald, so that their scheme for getting rid of Kennedy wouldn’t be exposed...
Well..., that was a mouthful... LOL..
