Just how many upcoming events does each candidate have near Orlando, Florida and Dayton, Ohio; how many bloggers are writing the phrase "voting for McCain" vs "voting for Obama"; and just how many times did Obama mention the word "pie" the other day in West Philly? Here's the latest meta-data from the social web...

Which campaign has the hotter grass-roots? One way to answer that question is to search for local events being organized by volunteers around the country and see who's got more things going on.

The top three Democratic campaigns make this really easy to do, with "find an event" tools on their sites. You can find Obama events here, Edwards events here, and Clinton's is smartly located on her home page. I guess the other campaigns either don't have a clue, or are afraid that if they gave supporters the freedom to list events, no one would. As it is, my quick research shows "Team Hillary" looks a lot like a Potemkin village.
