Vice Presidential hopefuls Tim Walz and JD Vance faced off in the last debate of the 2024 presidential campaign, focusing their attacks on the top of the ticket. They sparred over foreign policy, climate change, and immigration, with differing visions of American leadership overshadowing policy differences. Walz criticized Trump's leadership and failure to build a border wall, while Vance promised effective deterrence against Iran under Trump. Both candidates also criticized their running mates, Kamala Harris and Donald Trump, reflecting the fact that most voters don't base their vote on the vice president. They agreed that the number of migrants in the US illegally is a problem but blamed the opposing presidential nominee.
