Here, the author is using prolepsis to advise the reader that the rebuttal is anticipated and will be in the discussion. While doing this it leads to the appeal of logic, logos. It does this because once the opposition is reasoned it resonates within them and may give them a sense of understanding they may have not had before reading this article. Later on in the reading when Wagner illustrates the phone conversation with his mother it shows how they, personally, appealed to logic. Once they both gave their arguments on why they voted for their candidate they realized the reason they opposed each other's were for identical reason. Although this illustration was from an appeal of logos, it also, appeals to pathos; because it was a conversation with his mother it creates an emotional connection that will guide a reader to same realization as illustrated.
