@lerondagates,

The argument is telling us that "any impact this phenomenon has on election results is surely deleterious ..." meaning only in the case the viewer's perception of one's debate performance has an impact on the election, then it is deleterious but it is possible that it has no impact as well. (A) appears to be an attractive answer choice but it has no impact on the argument, it only tells us that voter's perceptions of the debate performance rarely affects national elections, but we are only interested in the case when it does affect the elections, and the stimulus argues that this is the scenario when the impact is deleterious. (D) weakens the argument because it demonstrates that when this phenomenon has an impact on elections, it cannot be said to be deleterious because there is actually a correlation between one's blinking rate and confidence, and confidence correlates with one's ability to perform well in a political office.

Let me know if this helps and if you have any further questions.
