Here's a link to a New York Times video about Chelsea Clinton's campaign appearances:
One thing I found particularly interesting is the reporter's comment on how Chelsea's appearances do not garner much attention except in local news coverage. This seems like a valuable approach for a national candidate to connect to people in local communities.
I was not able to attend Chelsea's appearance in Madison this week, but I hear the crowd was much larger than expected. Does this speak to interest in Hillary as a candidate or a "celebrity" factor? Perhaps people are attending to be a part of a significant event in the community.
