I read this in the New York Times today: "wide gaps in polls have historically tended to narrow in the closing weeks of the race". I read that ALL the time, but I've never seen an explanation for the phenomenon. Anyone know the answer? Wild guesses are fine, but a substantive answer is preferred...
