As the presidential debate on Sept. 10 between Donald Trump and Vice President Kamala Harris was likely the last between the two candidates, voters are turning their attention to a debate between the presidential candidates' running mates ahead of the 2024 presidential election.

What Happened: Tuesday's presidential debate was watched by 67.1 million people with Walt Disney Co (NYSE:DIS) unit ABC News hosting and allowing simulcasting to other media networks.

Other media networks have been fighting to get future presidential debates between the two candidates but they may be out of luck.

Trump posted on social media Thursday that there will be no third debate.

Without another debate between the two presidential candidates, attention could shift to vice presidential running mates J.D. Vance and Tim Walz, who are the candidates for the Republican and Democratic parties, respectively.

The two will face off on Oct. 1 in a debate hosted by CBS News, a unit of Paramount Global (NASDAQ:PARA)(NASDAQ:PARAA). Norah O'Donnell and Margaret Brennan will serve as the moderators for the debate.

Vance and Walz agreed to the debate and date set for New York City after several back and forth conversations with media networks.

Vance has sought to have as many debates as possible and accused Walz and Harris from running from media interviews.

"I think we ought to do as many debates as we possibly can," Vance previously said.  

Walz's team agreed to one debate and with Trump and Harris potentially not doing another debate, the opportunity for Vance and Walz to take part in more debates could arise.

What's Next: No rules have been publicly shared for the vice presidential debate, which makes forecasting a winner or what voters should expect tough.

The debate is expected to follow a similar 90-minute format and have commercial breaks, which could benefit Paramount.

Polymarket lists a 24% chance of having a live audience at the vice presidential debate, something that would differ from the 2024 presidential debates.

Vance has not been popular with voters since being named the vice presidential candidate as reported by The Hill. Vance's net favorability is negative and doesn't show signs of improvement. More voters (46.8%) view Vance unfavorably than those who view him favorable (39.8%).

Walz on the other hand has a positive net favorability rating with 43.6% viewing him favorably and 40.9% viewing him unfavorable.

The 2020 vice presidential debate between Mike Pence and Kamala Harris was watched by more than 57 million people. The total passed the 37 million total from the 2016 debate between Pence and Tim Kaine, CNN reported.
