Impact of Candidate Changes on Polling

The addition of Tim Walz as Kamala Harris's running mate has introduced volatility into the presidential race, prompting changes in polling dynamics. Brent Buchanan notes that despite Harris appearing to perform better than Biden, Trump has maintained his support levels, indicating a strong position. This is crucial as polls reflect not only current standings but also demographic shifts, with younger voters showing greater engagement with Harris. The findings reveal that a close race may favor Trump, as historical data suggests Democrats require a significant polling lead to ensure electoral success.
