Walz is currently enjoying a higher level of support among U.S. adults, maintaining a 36% favorability rating compared to Vance's 27%.
This is compounded by Vance's higher unfavorability rating among those polled, with 44% holding an unfavorable view compared to Walz's 25%.
Vance's popularity within the Republican Party is on the rise. In mid-July, only 3 out of 10 Republicans reported favorable feelings towards the Ohio senator as former President Donald Trump's running mate — 6 out of 10 didn't know enough about him.

The current polling finds that Vance's support within the Republican Party has doubled to 6 out of 10 among Republicans — mostly attributable to a rise in awareness about him and his policies.
Similarly, the AP-NORC poll found Walz maintains favorable opinions with 6 out of 10 Democrats, with approximately 3 out of 10 not knowing enough about him to form an opinion.

The Associated Press-NORC Center for Public Affairs Research poll was conducted from Aug. 8 to Aug. 12.
It surveyed 1,164 adults via the NORC "probability-based AmeriSpeak Panel," which it describes as "designed to be representative of the U.S. population." Its margin of error for all respondents is plus or minus 3.8 percentage points.
