Washington, DC- Last night was a difficult one for political pollsters in the United
States, including Ipsos. Almost without exception, the major polling agencies and their media
partners predicted that Hillary Clinton would win both the Electoral College and the popular
vote. As we all know now, Donald Trump won the Electoral College and is at a near-even split on
the popular vote (counting continues).
What we do know is that Donald Trump outperformed expectations in suburbia and rural
America, while Hillary Clinton’s failed to energize her potential coalition. What’s clear today is that
none of this was adequately reflected in the body of polling produced in the election; including
the polling from Ipsos.
As to why the polling didn’t pick up on the combination of forces that lead to Trump’s victory,
there are a number of theories being suggested today. Ipsos will conduct a thorough review of
these theories along with some ideas of our own. We look forward to sharing what we learn.
However, our initial working hypothesis is that this year was impacted by especially low voter
At the moment, counts suggest that only 52% of eligible voters cast a ballot this time,
compared to 59% in 2012. Our own public analysis predating the election showed clearly that an
average (60%) to a high turnout election would favor Clinton, while a low turnout election would
favor Trump. Our last polling assumed an average, but incorrect, turnout election (60%). We
presented this analysis in the media and other public forums.
Ipsos believes that scientific, responsibly-done polls are a valuable tool for gauging public
opinion and behavior, including during elections.
