Duncan is one of several Republicans who have spoken at the convention. The former Trump spokeswoman Stephanie Grisham made some news Tuesday night in a speech in which she said Trump called his own supporters “basement dwellers.” Ana Navarro, the CNN personality and former Jeb Bush aide, hosted part of Tuesday’s program. John Giles, who is the mayor of the conservative Arizona city of Mesa, and two former Trump voters spoke in the first half of the week, and former Representative Adam Kinzinger is scheduled to do so this evening. Many conventions have featured a speaker from across the aisle—think Joe Lieberman’s backing of John McCain in 2008 or John Kasich’s support of Joe Biden four years ago—but the number of Republicans at this DNC is remarkable.
