 For NPR News in the Twin Cities, I'm Emily Reese. At day one of the Republican National Convention yesterday, former President Donald Trump named Ohio Senator J.D. Vance as his running mate. David Hand, Minnesota's Republican Party chair, was one of the state's delegates in Milwaukee. He thinks the 39-year-old is a good pick to help carry the party's baton. This is not the same party that we saw when Ronald Reagan was president. Things have changed.
