JD Vance and Tim Walz are set to do battle for what looks to be the final debate of this US presidential election.
The vice-presidential candidates will meet for their only debate in New York today, which gets underway at 2pm NZ time.
US political commentator Danielle McLaughlin says the buzz could reach the levels of Joe Biden vs Sarah Palin in 2008.
She told Ryan Bridge vice-presidential picks are normally safe, but Walz and especially Vance are really out of the mainstream.
McLaughlin says Vance has been attacking cat ladies and Taylor Swift and has repeatedly spread crazy rumours about Haitian immigrants eating pets in the mid-west.
