Bernie Sanders' real first name is Bernard. (But his insistence on being called "Bernie" initially caused some problems for newspapers like the New York Times, which historically had called candidates by their actual first name-- Charles, rather than Charlie, for example. But Senator Sanders instructed all the media outlets to refer to him as Bernie, rather than Bernard; that is why you only see him being called "Bernie Sanders" and not Bernard Sanders.) And interestingly, Senator Sanders does not have a middle name.
