Using this trendy tool, I found that the volume of news references to “Barack Obama”, “John Edwards” and “Hilary Clinton” appear to be in line with the Washington Post’s election results, as pictured below.

The Republican race appears to be no different: the sheer volume of references to any particular candidate appears to have been a leading indicator in determining the caucus winners in Iowa. Media tycoons are constantly reminding just how much power they have in democratic regimes.

Lastly, another striking comparison: Britney Spears has been consistently higher in search volume than Barack Obama all year, even though there have been fewer news references to her.
