Tim Walz and JD Vance will meet for their first and possibly only vice presidential debate Tuesday, in what could 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 two-term Democratic governor of Minnesota, the chance to introduce themselves, make the case for their running mates, and go on the attack against the opposing ticket. Tuesday's matchup could have an outsized impact. Polls have shown Vice President Kamala Harris and former President Donald Trump locked in a close contest, giving added weight to anything that can sway voters on the margins, including the impression left by the vice presidential candidates. It also might be the last debate of the campaign, with the Harris and Trump teams failing to agree on another meeting.
