It’s believed US voters will be more concerned about records than personalities heading into today's vice-presidential debate. 

JD Vance and Tim Walz will meet for their only debate in New York today, getting underway at 2pm NZ time. 

Key issues expected to be on the agenda include the economy, cost of living, and border security. 

Republican strategist Matt Terrill told Heather du Plessis-Allan if Vance focuses on those, he'll have a much better night than Walz. 

He says many voters will be questioning if they're better off today than they were four years ago.
