Gallup, whose final 2012 election poll showed Republican challenger Mitt Romney leading President Barack Obama, said today that its likely-voters screen and too few interviews on the East and West coasts contributed to its failure to forecast the final vote accurately.
The Gallup poll commissioned a study of its methods after its last pre-election survey gave Romney a one-point lead, 49 percent to 48 percent, over Obama, who won re-election by almost four percentage points.
