I looked around and tabulated all the polls for
primaries (only) that SurveyUSA did and also the final results and compared
them.

In the big states of Ohio and California, SurveyUSA
was dead accurate with the percentages (and winners of course). In the big state of Texas, they
actually were wrong about the winner as well as in Missouri.

Of all the states listed, SurveyUSA had
underestimated Obama's election showing 10 times, overestimated 2 times, and
were right 2 times. Underestimation: 2-12%, average of 4.8%.
Overestimation: 1-2%, average of 1.5%.


Of all the states listed, SurveyUSA had
underestimated Clinton's election showing7 times, overestimated4
times, and were right3 times. Underestimation: 1-5%, average of
2.29%. Overestimation: 3-6%, average of 4.25%.
