Critical Reasoning

2,500 individuals of voting age were polled and asked where they stood on the political spectrum. 78% of these individuals described themselves as "moderate" in their political views; however, in the national elections that most closely preceded and followed the poll, over half of the individuals polled voted for candidates far to one end of the political spectrum. It follows that these individuals did not accurately describe their political views.

Which of the following is an assumption on which the above argument relies?

A. Individuals always characterize themselves in keeping with their actual political views.
B. There were no moderate candidates in the national elections preceding and following the poll.
C. Voters with moderate political views will not vote for candidates who do not express moderate political views.
D. Voters can be highly fickle, changing their political views in a relatively short period of time.
E. Many of the polled individuals did not understand what a moderate political view is, and so misdescribed themselves

OA is c i have seen this question before on this forum but still i am confused. the conclusion is that voters actually didn't describe their political views correctly, however C says that voters with moderate political views will not vote for candidate who do not express moderate views. it means that the voters with moderate views actually didnt vote. this weakens the conclusion.
