Speaking on condition of anonymity, CIA psychiatrists speculated that John McCain's decision to vote 'no' on the Republican Graham/Cassidy health bill was the result of subtle brainwashing during his extended confinement as a prisoner of war in North Vietnam.
The psychiatrists reasoned that the North Vietnamese expected that a long line of Republican presidents, all with an anti-Viet Cong attitude, would follow the election of Richard Nixon. McCain, the communists believed, would surface as a potential presidential candidate early in the 21st century. Their brainwashing techniques, patterned after those used by the North Koreans and Chinese in the 1950s, were designed to mold McCain's views on political issues decades after his imprisonment. What his captors didn't anticipate was the development of closer relations between the U. S. and Vietnam before McCain had risen to the presidency.
"The 'no' vote on the health bill is merely a manifestation of the anti-establishment brainwashing that he underwent during captivity," one psychiatrist suggested.
