ST. PAUL, Minn. (AP) — Minnesota Public Radio and the University of Minnesota’s Humphrey Institute say they’ll be taking a close look at how they conducted polls before the election.
They said in a statement Thursday the process will include an internal review by the Humphrey Institute, and an independent audit by Frank Newport, the editor and chief of Gallup.
The MPR-Humphrey Institute polls were accused of consistently overstating support for Democratic gubernatorial candidate Mark Dayton.
The final pre-election poll gave Dayton a 12-point lead over Republican Tom Emmer. But Dayton’s lead in the voting was under half of 1 percentage point, pending a recount.
MPR and the Humphrey Institute say they’ll be looking at whether there’s a problem with their methodology or if other factors explain the difference.
