WASHINGTON (AP) — Tim Walz and JD Vance will meet for their first and possibly only vice presidential debate Tuesday. It may also be the last debate for both campaigns to argue their case before the election. The debate in New York hosted by CBS News will give Vance, a Republican freshman senator from Ohio, and Walz, a Democratic former congressman and two-term governor of Minnesota, a chance to make the case for their running mates, former President Donald Trump and Vice President Kamala Harris, and go on the attack against the opposing ticket. Vice presidential candidates and the lone debate they typically engage in have not historically had a huge impact on the presidential race, but this matchup could have an outsized impact.
