Minnesota Governor Tim Walz and Ohio Senator JD Vance will face off in their first and only vice-presidential debate on Tuesday. Historically, vice-presidential debates haven't shifted elections significantly, but this year’s contest could be different, as Walz and Vance take the stage in a highly polarized political landscape. While Walz has gained national attention for his unconventional style of labeling rivals “weird,” Vance has drawn controversy for his harsh immigration rhetoric. The debate comes amid renewed focus on the role of the vice president after two recent assassination attempts against Donald Trump.
