This conspiracy theory mocks itself. The idea that Vladimir Putin sat in the Kremlin, steaming over Benjamin Cardin’s report on Russia, and thus developed a dastardly plot to rid himself of his daunting Maryland nemesis – “I know how to get rid of Cardin: I’ll have a trans woman who was convicted of felony leaking run against him!” – is too inane to merit any additional ridicule. But this is the climate in Washington: no conspiracy theory is too moronic, too demented, too self-evidently laughable to disqualify its advocates from being taken seriously – as long as it involves accusations that someone is a covert tool of the Kremlin.
