The next group, whose names are more familiar and whose faces you see frequently on the nightly news, need to broaden their appeal to the electorate. Most in this group have focused on a few issues, with somewhat detailed proposals, but need to widen the range of their vision. Pete Buttigieg, mayor of South Bend, Indiana, is one of this group who needs to put together a stronger vision in order to succeed. For the rest of those who appeared on stage this week, if they didn't fall into one of the previous categories, default to this level. All need to work on their campaign strategies.
