I don't think there us anything in the passage to suggest that the polls were not accurate that's why I didn't choose D.
E....the passage states that the losing candidates were advised avoid early spending and instead saved funds for television advertisements late in their campaigns. Its possible that the losing candidates didn't follow that advise and hence lost suggesting that a pitch in the later stages of election is more effective than the ones at the beginning.
Tats wat E states ... Candidates
