The significance and importance of the VP debate between Vance and Walz are heightened.

The upcoming vice presidential debate carries significant importance with a slim margin in the polls and no immediate plans for a second face-to-face meeting between Vice President Kamala Harris and former President Trump.

The upcoming face-off between Republican vice presidential nominee Sen. JD Vance of Ohio and Minnesota Gov. Tim Walz, the Democrats' nominee, on Tuesday will have heightened stakes as the undercard of a White House race.

An unexpected major blow or misstep could transform a typically minor event into a significant confrontation.

As the last direct meeting between the two tickets before the election and the only head-to-head matchup between the principal candidates, this debate is highly significant, according to longtime Republican strategist and communicator Ryan Williams, who has experience in multiple presidential campaigns.

Political pundits and debate watchers agreed that Harris outperformed Trump in their first and final debate last month.

A boost could be given to Trump by a strong showing from Vance in Tuesday's vice presidential debate.

And there's a precedent from twelve years ago.

The well-regarded performance of Vice President Joe Biden in the running mate debate against Romney running mate Rep. Paul Ryan gave the Democrats' ticket a big boost after a shaky first debate by then-President Barack Obama against 2012 GOP presidential nominee Mitt Romney.

On the campaign trail, Vance, a 40-year-old vice presidential candidate, has been very vocal, participating in numerous interviews and answering questions from reporters.

Walz, at 60, has become increasingly hesitant to engage with the national news media.

In preparation for the upcoming showdown, the governor has been attending debate camp with advisers and Transportation Secretary Pete Buttigieg, who portrayed Vance in mock debates, in Harbor Springs, Michigan.

Also helping out - Walz's wife - Minnesota First Lady Gwen Walz.

Walz revealed to reporters on the eve of the showdown with Vance that his wife had been assisting him with debate preparation and he had won every debate.

Vance has been participating in murder board sessions with his team for the past month, where a group of people engage in tough questioning and open discussions to help someone prepare for a challenging examination or test, including a vice presidential debate.

Last week, Vance engaged in a mock debate with Rep. Tom Emmer of Minnesota, who portrayed Walz, and former Trump administration Treasury Department assistant secretary Monica Crowley, who served as one of the moderators from CBS News, which hosted the event in New York City.

During the mock debate, a storm hit Cincinnati, Ohio, where Vance lives and where the prep session was held. Despite the power outage, Vance and the team continued with the session, using lanterns for lighting and cellphones for timers, according to the source who first shared the details with Planet Chronicle.

Walz and Emmer served together in the House for four years before Walz became Minnesota's governor in 2018. "I know him well," Walz said.

Emmer criticized Walz, stating that the most challenging aspect of playing him is maintaining a straight face while lying, as Walz excels at debates but lacks substance.

Trump stated on Monday that he had not given his running mate any advice, as he believed he didn't require it.

He mentioned that he and Vance had been conversing and that he believed the senator was in good health.

The Trump campaign plans to increase anticipation for Walz prior to the debate.

On Monday, Jason Miller, the Trump campaign senior adviser, stated that Tim Walz is very good in debates. He emphasized that Walz's skills were really good and that he had been a politician for nearly 20 years. Miller added that Walz would be very well prepared for tomorrow night's debate.

Walz comes into the debate with better poll numbers than Vance.

The latest Planet Chronicle national poll shows Walz's favorable rating at 43% and his unfavorable rating at 40%.

Vance stood in negative territory, at 38%-50% favorable/unfavorable.

On Monday afternoon, the senator arrived in New York City and later in the evening, he headlined a gathering of GOP mega donors, taking a break from debate preparations.

On Tuesday, Walz had a flight scheduled to New York City, prior to the debate.

The "CBS Evening News" anchor and managing editor Norah O'Donnell and "Face the Nation" host and chief foreign affairs correspondent Margaret Brennan are moderating the vice presidential debate.

The 90-minute debate, starting at 9pm ET, will be held at the CBS News broadcast center in New York City.

The Planet Chronicle Channel, Fox Business Network, Planet Chronicle Digital, Planet Chronicle Audio, and Fox Nation will broadcast special programming of the debate.

The Harris and Trump campaigns agreed to two four-minute commercial breaks during the debate, during which campaign staff are not permitted to interact with the candidates.

The upcoming debate between President Biden and Donald Trump will follow the same rules as the September 2020 Harris-Trump debate and the June 2021 debate between Trump and President Biden.

The microphone of a candidate will not be muted when their opponent is speaking.
