 And the big question now, who will she choose as a running mate? CBS's Nancy Cordes with the short list. Governor Roy Cooper of North Carolina. She campaigned with him last week. They were state AGs together. They go way back. Governor Josh Shapiro of Pennsylvania. She just campaigned with him, too. Governor Gretchen Whitmer of Michigan. Senator Mark Kelly of Arizona. And then I throw in Andy Beshear of Kentucky. He's a popular Democratic governor in a red state. CBS News special report. I'm Cammie McCormick.
