Eric Ostermeier at the U of M’s Smart Politics says “not really.”
However, Coleman’s unfavorability numbers in the new SurveyUSA poll (44 percent) were also at their lowest point going back to April 2008 (42 percent, Rasmussen). In fact, Coleman’s favorability numbers are actually up 2 points from the last time SurveyUSA asked the three-response option question, back in October 2007 (from 36 percent; though his unfavorability numbers rose by 7 points during that span).
Ostermeier says Al Franken’s net favorability rating has suffered since Election Day.
