Poor Joe Biden. He gets fewer Google searches than that Jesus guy–whatever he‘s running for.
Google Trends is a nifty proxy for measuring public interest in a very narrowly defined subject. The examples above show “Search volume” (the total number of Google search queries for each keyword) and “News reference volume” (the same for news stories) for the last twelve months in the U.S. The lettered boxes indicate news stories tagged by keyword–which I have omitted from this screenshot for the sake of simplicity.
