Teabaggers causing problems for the GOP, and Democrats?

Virginia Governor and Democratic National Committee Chairman Tim Kaine recently commented on the so-called Tea Party movement, and believes that his party will benefit from the fringe group's attack on moderate and conventional Republican figures. On MSNBC's Countdown with Keith Olbermann, David Shuster spoke with Arianna Huffington who agreed with Governor Kaine that the Teabaggers were causing for Republicans who face party primaries, but also added that the Democrats might not necessarily benefit in the 2010 midterm elections.
