Two mathematicians
have devised what they say is a “surprisingly effective” means to
predict the outcome of the U.S. presidential election using median
statistics based on voter polling. In a paper in the journal
Mathematical and Computer Modeling, Wes Colley, of the University of
Alabama, Huntsville, and J. Richard Gott III, at Princeton
University, said they have developed a system that uses the margins
of victory for each candidate in each of the many polls taken during
the past month.
Those margins are then ranked from the largest
margin to the smallest, and the middle number, or the median, is
used as the candidate’s score for the individual states. Colley is
nationally known for his computer modeling system used in
determining college football rankings by the NCAA, and his new
system has Barack Obama ahead of John McCain."John McCain needs several swing states to break his way, whereas
Obama can afford to lose a couple and still win the election,"
Colley said.
Before the Obama supporters start breaking out the
champagne, however, they should be aware of new research from the
Maryland-based Institute for Operations Research and the Management
Sciences (INFORMS), the world's largest society for operations
research professionals. Using a methodology that "applies a
mathematical model of state polling data, using a dynamic
programming algorithm to forecast electoral results," INFORMS has
McCain ahead by as many as 27 electoral votes (282.8 votes for
McCain, 255.2 for Obama).
Then there is University of New Hampshire
Survey Center founder and former Gallup Poll managing editor David
Moore, who is revealing in a new book that "media polls are not used
to uncover the 'will' or thoughts of the public, but rather to
manufacture a public 'opinion' that grabs the attention of
journalists and can be used to fill media news holes." The
methodology used by the major national polls, he says, "give false
readings of which candidates voters prefer and what the public
wants."
