What are your numbers supposed to mean? From your article:
Prior to the debate, a New York Times/Siena College poll released Sept. 28 found Midwestern voters prefer Walz to Vance: Walz was viewed favorably by 44% of voters and unfavorably by 41%, while Vance was viewed favorably by 42% of voters and unfavorably by 48%.
So 44% like Walz, 42% like Vance. 41% dislike Walz, 48% dislike Vance. Comparing 42 and 41 is comparing two different things
42%. That’s how many debate viewers in the CBS poll thought Vance was the winner of the debate, compared to 41% who thought Walz won. Seventeen percent of viewers said the debate ended in a tie.
