The Clinton campaign is out with a new Web video.
WASHINGTON (CNN) - Four days after Barack Obama's presidential campaign launched a wildly popular Web video showing a former Hillary Clinton backer in Iowa switching her allegiance to the Illinois Democrat, the Clinton campaign hit back with its own online video of current supporters once aligned to rivals.
The two-minute video called "Switchers" includes interviews with several former supporters of either Obama or John Edwards, in which they describe why they decided to defect to Clinton.
The Obama Web video released Friday documented why one Iowa precinct captain decided to reverse her support of Clinton in favor of Obama. That video has been viewed more than 340,000 times on YouTube.
