On the Republican side I actually had to separate out them individually, because Ron Paul has astronomical web hits when compared with even the biggest candidates on their side.
This is poetic justice:
Ron Paul
Rudy Giuliani

Mike Huckabee

Fred Thompson

Mitt Romney
http://www.google.com/trends?q=ron+paul%2C+mitt+romney&ctab=0&geo=all&date=2007&sort=0 Ron Paul
John McCane

Ron Paul
Duncan Hunter
http://www.google.com/trends?q=ron+paul%2C+duncan+hunter&ctab=0&geo=all&date=2007&sort=0Our side was much easier, the top three crushed the lower tiers, so you can look the 1st line v. 2nd line if you want to, but it's not easy to read.
Clinton
Obama
Edwards
http://www.google.com/trends?q=hillary+clinton%2C+barack+obama%2C+john+edwards&ctab=0&geo=all&date=all&sort=0If you look at January 2008, Edwards really falls off:
Clinton
Obama
Edwards
http://www.google.com/trends?q=hillary+clinton%2C+barack+obama%2C+john+edwards&ctab=0&geo=all&date=2008-1&sort=0He was doing well throughout 2007, always neck and neck with the other two in searches:
Clinton
Obama
Edwards
http://www.google.com/trends?q=hillary+clinton%2C+barack+obama%2C+john+edwards&ctab=0&geo=all&date=2007&sort=0But you'll notice Obama really take off right at the end there, while Clinton and Edwards are down where they were before.
