Obama Favorability 25 Points Higher Among Cell Phone Respondents Than Home-Phone Respondents in SurveyUSA Polling, 16-Points Higher in Marist Polling.
The Marist College Institute for Public Opinion is the only other pollster, besides SurveyUSA, to include routinely in its poll releases, the difference between cell-phone respondents and home-phone respondents. This permits an analysis of how SurveyUSA and Marist polls compare to the many polls still being released, by other research companies, with no cell-phone respondents.
- In nationwide polls of registered voters released simultaneously this week, Marist found a 16-point difference in how cell-phone respondents and home-phone respondents see Barack Obama, SurveyUSA found a 25-point difference.
- There is a limited difference, of 5 points, in how cell and home respondents view Mitt Romney in SurveyUSA polling.
- But there is a 23-point difference in how cell and home respondents view Newt Gingrich, in SurveyUSA polling.
- Polls of landline (home-phone) respondents only, will overstate Gingrich support, will understate Obama support.
Polls that exclude cell-phone respondents, such as those conducted by many SurveyUSA competitors, risk mis-characterizing public opinion. SurveyUSA estimates that by Election 2012, half of voters age 25 to 34, and one-third of voters age 35 to 44, will not be reachable on a home-phone. Make certain the polls you commission, and the competing polls you analyze, properly account for cell-phone respondents. No research firm has done more work studying cell-phone respondents at the state and local level than has SurveyUSA, America’s Pollster®.
