Democrats have the early lead in the blogosphere, generating more buzz, or online mentions in blogs and discussion, by nearly a 2-1 ratio, according to Nielsen BuzzMetrics. With no online advertisements, Senator Obama has created the greatest Buzz volume overall. Senator Hillary Clinton, coming in a distant second, has used unique techniques to close the gap such as the recent online parody of the Soprano's series finale to generate additional buzz.
John McCain is leading Republicans with online buzz, potentially because of his heavy online ad spending in recent months. McCain is followed relatively closely by Rudolph Giuliani and Mitt Romney, and distantly by Ron Paul.
The buzz for the Republican party overall is related to the heated discussion between Ron Paul and Rudolph Giuliani during the Republican debate in May 2007.
Senator Clinton's campaign, which appears to have spent much less, generated the second most website traffic, behind Democrat Senator Barack Obama.
Obama, with no online advertisements, dominated the pageviews of all candidates, with the Obama'08 website generating nearly 4 million pageviews from almost 650,000 unique visitors in April.
