  In July 2024, a CNN poll analysis after the Republican National Convention showed a net-negative approval rating for Vance. That week, Vance's middling public reception and other concerns led some prominent Republican politicians and political analysts to say that he may have been a poor choice of running mate, especially in light of the shift in the election's dynamics upon the withdrawal of President Biden from the election and advent of Kamala Harris as the Democratic nominee.
  
  After the October 2024 vice-presidential debate, A CBS News/ YouGov poll of 1,630 likely debate viewers found Vance's favorability rose from 40% to 49%, while Walz's increased from 52% to 60%. Both candidates' unfavorability ratings also declined, with Vance's dropping from 54% to 47% and Walz's falling from 41% to 35%. The poll had a margin of error of 2.7 points. As of February 20, 2025, according to FiveThirtyEight, Vance's overall favorability was 40.7% and his unfavorability was 42.5%.
