Democrat Tim Walz and Republican JD Vance, two sons of America's Midwestern heartland with deeply opposing views on the issues gripping the country, shook hands on Tuesday night to start the only vice presidential debate of the Nov. 5 election.
Walz, 60, the liberal governor of Minnesota and a former high school teacher, and Vance, 40, a bestselling author and conservative firebrand US senator from Ohio, are expected to clash early and often, with each trying to land a lasting blow in an event that has historically had little measurable impact on White House campaigns.
Aides to the two men predicted fireworks during the 90-minute televised debate at the CBS Broadcast Center in New York, as they defended themselves and spoke up for the candidates at the top of each ticket, Democratic Vice President Kamala Harris and Republican former President Donald Trump.
Walz has called his Republican opponents "weird," and Vance came under fire for past comments disparaging some Democrats as "childless cat ladies."
Harris and Trump were expected to watch the debate, which began at 9 p.m. (0100 GMT on Wednesday), and Trump said he would offer a play-by-play commentary of the event on social media.
Harris was widely viewed as the winner of her sole debate with Trump on Sept. 10 in Philadelphia, which was watched by an estimated 67 million people.
That square-off did little to change the trajectory of an extremely close election battle. While Harris has edged ahead in national polls, most surveys show voters remain fairly evenly divided in the seven states that will decide the November election.
Political analysts say vice presidential debates can be fiery but generally do not alter the outcome of an election. That said, even a slight shift in public opinion could prove decisive with the race on a razor's edge five weeks before Election Day.
The main takeaway from the last V.P. debate, the 2020 encounter between then-Senator Harris and then-Vice President Mike Pence, was a fly that landed on Pence's head unbeknownst to Pence himself.
With no more debates planned, the stand-off allows Walz and Vance to make closing arguments on behalf of their campaigns - just as early voting ramps up across the country.
MUD-SLINGING
Walz, who has sought to cultivate a homespun image as a former high school football coach, is expected to get Vance to defend his 2021 comments criticizing Harris and other Democrats as "a bunch of childless cat ladies who are miserable at their own lives."
Walz is also likely to go after Vance for spreading a fictional story of Haitian immigrants eating household pets in Springfield, Ohio, a false claim that Trump has repeated and that local officials say has drawn bomb threats.
The Democrat will seek to introduce himself to U.S. voters who may not be familiar with him while aiming to keep the conversation focused on Harris' agenda, said a Walz adviser who asked to remain anonymous to discuss strategy.
Trump advisers said Vance will try to force Walz to defend the Biden-Harris administration's policies on immigration and the economy, as well as his own handling of the riots in Minneapolis in 2020 after the death of George Floyd, a Black man, at the hands of a white policeman.
Vance will also bring up questions about Walz's military service, said Tom Behrends, a retired command sergeant major who joined a Trump campaign call about the debate.
Republicans have accused Walz of exaggerating his final rank in the Army National Guard, where he served for 24 years. In the past, Walz described himself as a retired command sergeant major, one of the highest non-commissioned officer positions in the Army.
While he achieved that rank, he did not meet the requirements to retire with that title.
The Harris campaign says also Walz "misspoke" in 2018 during his gubernatorial campaign in Minnesota when he referred to "weapons of war, that I carried in war." Walz was never deployed to a war zone.
Vance is a former Marine who served as a military journalist. He was deployed to Iraq but never saw combat.
Earlier on Tuesday, Minnesota Public Radio reported that Walz was not in China during the 1989 Tiananmen Square crackdown as he had previously claimed but travelled there months later, another misstatement likely to draw Vance's fire.
Despite Vance's having written "Hillbilly Elegy," a popular 2016 memoir, US voters have a negative view of him, Reuters/Ipsos polling shows, with 51% of registered voters saying they view him unfavourably, compared with 39% who view him favourably. Meanwhile, Walz was viewed favourably by 44% of registered voters, with 43% reporting an unfavourable view in the Sept. 20-23 poll.
