Early last week, Michael Barone published a piece analyzing the election returns in which he focused on the manner in which “the double-negatives” — those who thought highly neither of Donald Trump nor of Hillary Clinton — broke at the very end decisively for the former. Here is the way he put it:

One reason polling may have been misleading, or at least misled many of us in the psephology racket, is that this is the first presidential election since random sample polling began in 1935 in which most voters had negative feelings toward both major party candidates.

Election analysts have had experience dealing with elections in which majorities have positive feelings about both nominees; that has usually been the case in contests which turn out to have been seriously contested. “Double positives,” people with positive feelings about both candidates, will usually split along partisan or perhaps ethnic lines, and ordinarily pretty evenly.
