USA Today and Gallup are ending their 20-year polling partnership, both organizations announced Friday.
The two organizations have been partners since 1992.
The Washington Post's Aaron Blake reports:
Recently, Gallup’s methodology has been attacked by analysts and other pollsters, whose poll results differed starkly from Gallup’s toward the end of the 2012 presidential campaign. In 2006, Gallup parted ways with CNN in a pretty messy split. Gallup cited the network’s “low ratings,” while CNN called the assertion “unprofessional” and “untrue.”
Gallup's editor in chief, Frank Newport, said in November that Gallup was reviewing its performance after its final poll showed Mitt Romney ahead of Barack Obama -- a result that raised questions about its likely voter model.
Gallup called the split a "mutual decision to move in independent directions," and said it would "evolve the polling it conducted in partnership with USA Today," while USA Today said it was "in the final stages of negotiating an arrangement with another polling organization."
