There are now 20 Democratic candidates for president in 2020. Six are United States senators. One is the former governor of Colorado, and one is the current governor of Washington state. Two are mayors—one of South Bend, Indiana; the other from Miramar, Florida. We now have Joe Biden, who served as vice president under Obama and was previously a senator from Delaware. Add to this list two others—one who says she is a spiritual leader and author, and another who says he is an entrepreneur.
