Something to consider...

In 1948, Gallup screwed with the weighting, assuming the republicans would turn out much in much larger numbers than the democrats, but they were wrong, and badly miscalled the election. In 1952 Gallup assumed the other way, that the race would be tight and down to the wire, but they blew that call as well. In 1976, Gallup assumed the opposite, that democrats would overwhelm republicans because of Watergate, but when it became obvious that republicans would vote anyway, Gallup had to change its model to show their participation more accurately. In 1980, Gallup called Carter ahead until the very end, when they grudgingly granted Reagan a small lead, yet another case where Gallup's assumptions were well off the mark. In 1996, Gallup overstated Clinton's support and understated Dole's support throughout the campaign, and in 2004 Gallup called the race too close to call.
