the CIA was created in 1947, just after ww2.
about the same time, the progressive party, which had been one of the main parties since the early 1900s, disappeared due to their cozy relationship with the nazi party prior to ww2.
this allowed them to maintain power while hiding.
the re-emerged around 1960 inside the democrat party... causing then big dem leader Ronald Reagan to switch to a republican. when asked why he left he said, “i didn’t leave the democrat party... the democrat party left me.”
i also believe they progressives had JFK killed in order to distract the populace and weasel their way deeper into govt.
by the late 70s/ early 80s, they started making in-roads to the republican party with the ‘big tent’ republicans.
today, they’re in both parties and infest many of the major govt institutions.
Teddy Roosevelt’s Progressive party was pretty much moribund after Sen. Bob LaFollette lost his third-party bid for the White House in 1924. After 1932, the party pretty much disappeared and many of its members became ardent New Dealers.
Henry Wallace founded a new Progressive Party for his presidential bid in 1948, but that one finally disbanded in 1955.
Reagan had switched parties long before he registered as a Republican
Truman in 1948 was his last democrat vote, Reagan then started campaigning as a democrat for republicans (Eisenhower).
