If all presidents are paranoid to a certain degree -- which they are, apparently -- then where does President Donald Trump rate on the paranoia scale?

High, according to Patrick J. Sloyan, a journalist who covered nine presidents between 1960 and 2011. His essay published today by Columbia Journalism Review ("Trump sets a new bar for presidential paranoia") looks not only at the president's paranoia, but also those of Richard Nixon, Lyndon Johnson and others.

Sloyan's opening anecdote about LBJ calling a wire-service reporter to complain about a missing letter -- and, thus, altered meaning -- of a single word in a news story is classic presidential fear of public reaction to a minor thing. It's also entirely believable.
