… What Are Joe Biden’s Fixed Principles? (Hat tip, Dave Lull.)

The problem with a politician having no known beliefs is that it becomes difficult to believe him on nearly any subject apart from those touching on his own self-interest. This becomes especially so in the age of the speechwriter, when a politician is no longer the author of words for which he is held fully responsible. In his public appearances, Mr. Biden, who is properly chary of giving press conferences lest he lapse into one of his infamous gaffes, has come more to resemble the puppet in a ventriloquist’s act.
