WASHINGTON (AP) — Vice presidential nominees JD Vance and Tim Walz have used their time on the debate stage to focus the bulk of their attacks not on one another, but on those at the top of their rival tickets. Republican Vance and Democrat Walz both sought to project themselves as genial opponents as they lobbed criticism at Harris and Trump, respectively. With the Mideast in turmoil, the two vice presidential candidates offered different approaches toward foreign policy: Walz promised “steady leadership” under Harris while Vance pledged a return to “peace through strength” if Trump is returned to the White House. The two running mates agreed that the number of migrants in the U.S. illegally is a problem. But each laid the blame on the opposing presidential nominee.
