John McCain is the Manchurian Candidate

If you have ever seen John McCain speak candidly, without a script, he seems like a big eyed zombie. A blank smile and a long time to respond makes it even worse when he misunderstands a question.

When he spoke at the New School in Manhattan, a student had amazingly got a copy of his planned speech. She spoke before him and presented a point by point counter speech. He came up after and gave his exact planned speech as if no one would notice the previous speech.

He is being controlled by Vietnamese/Soviet scientists rather than the Chinese in the movie.
