Now it’s Sen. Hillary Clinton’s turn to explain remarks at a private fund-raiser.

On a tape released by the Huffington Post, Clinton bashes MoveOn.org and the Democratic Party’s “activist base” for “intimidating” her supporters.

“We have been less successful in caucusing because it brings out the activist base of the party,” Clinton says on the muffled audio recording. “You know, MoveOn.org didn’t want us to go into Afghanistan. I mean, that’s what we’re dealing with, and they turnout in great numbers and, um, they are very driven in their view of our positions. And it’s primarily national security and foreign policy that drives them. I don’t agree with them. They know I don’t agree with them. Though they flood into these caucuses and dominate them and really intimidate people who actually show up to support me.”

On the tape, which the Web site said was made at a February fund-raiser, Clinton says that her Democratic rival, Sen. Barack Obama, was better at using the Internet and had gotten a number of “breaks,” including the endorsement by MoveOn.org that resulted in “a gusher of money that just never seems to slowdown.”

The Huffington Post quoted a Clinton spokesman confirming the tape’s authenticity, and reaffirmed the accusations of intimidation. A Clinton was not immediately available to comment for Washington Wire.

A week ago, the Huffington Post carried controversial statements at another private fund-raiser – by Obama. His comments about “bitter” small-town Pennsylvanians who “cling” to guns and religion dominated the campaign this week.
