One thing I do remember about Ohio is that Obama under-performed his poll numbers on Super Tuesday.
Surprisingly, this wasn't really the case.
Clinton's final margin in Ohio was 8.65%. The
March polls were:
SurveyUSA: Clinton +10
ARG: Clinton +14, Clinton +7
PPP: Clinton+9
Suffolk: Clinton+12
Rasmussen: Clinton+6
Quinnipac: Clinton+4
Zogby: Tie and Obama+2
The average of the non-Zogby polls was Clinton +8.86%. That of the non-Zogby, non-ARG polls was Clinton +8.2%.
So while you can safely say that Obama underperformed his Zogby numbers, the rest of the polls were pretty accurate.
