As noted on the frontpage, Clinton railed on MoveOn shortly after Super Tuesday stating, in part, that "they [MoveOn] flood into these caucuses and dominate them and really intimidate people who actually show up to support me."

According to HuffPo:

Howard Wolfson, communications director for the Clinton campaign, verified the authenticity of the audio, and elaborated on Clinton's charge that these same party activists were engaged in acts of intimidation against her supporters: "There have been well documented instances of intimidation in the Nevada and the Texas caucuses, and it is a fact that while we have won 4 of the 5 largest primaries, where participation is greatest, Senator Obama has done better in caucuses than we have."
