In 2012, Gallup incorrectly predicted that Mitt Romney would win the 2012 U.S. presidential election.[33] Following the results of the election, Gallup spent six months reviewing its methodology.[33] The company concluded that its methodology was flawed as it made too few phone calls in Eastern and Pacific time zones, overestimated the white vote, and relied on listed landline phones that skewed the sample to an older demographic.[33]
