Google Trends is a neat little tool created by Google to chart how popular a search term has been over a given length of time–in the standard search, it's a few years' time. The tool then links spikes in search volume to news stories that came out about the time of the spike in public interest in the term. It also tells the top three cities where people are looking for this term. I ran the full names of the top democratic candidates through this tool and I'll share the results with you in no particular order.
