 I'm Daria Ulbiger. Ohio Senator J.D. Vance makes his first appearance as the party's vice presidential nominee to cheers and applause, but some are worried about his inexperience. 39-year-old J.D. Vance has held elective office for only two years, and some here at the GOP convention think that's a problem. Chris Fustner says the Democrats chose an underqualified vice presidential candidate in 2020. They're number two, cannot take over. We are doing the same mistake.
