By BILL BARROW, ZEKE MILLER and NICHOLAS RICCARDI WASHINGTON (AP) — Vice Presidential hopefuls Tim Walz and JD Vance squared off Tuesday night in what may be the last debate of the 2024 presidential campaign. It was the first encounter between Minnesota’s Democratic governor and Ohio’s Republican senator, following last month’s debate between the tops of their tickets, Vice President Kamala Harris and former President Donald Trump. No more debates are on the political calendar before Election Day.
