Sen. Hillary Rodham Clinton's (D-N.Y.) top advisers, doing damage control after the candidate's debate performance Tuesday, told supporters on a conference call Wednesday that the campaign needed more money to fight back.

Mark Penn, Clinton's senior strategist and pollster, and Jonathan Mantz, the campaign's finance director, told the supporters on the call, which The Hill listened to in its entirety, that they expect attacks from Clinton's rivals to continue, and she will need the financial resources to deflect their attacks.

Clinton came under withering assault in the Philadelphia debate, and some supporters on the call agreed with analysts that she stumbled.

"I wouldn't say she lost her cool," one caller said. "But I would say she lost her footing."

The caller addded that Clinton's response to questions about records from her time in the White House that have been sealed by the National Archives "made me roll my eyes."

The criticisms followed Penn's assertion that Clinton was "unflappable." He also said criticisms from Sen. Barack Obama (D-Ill.) and former Sen. John Edwards (D-N.C.) would backfire and that he was already "detecting some backlash," particularly among female voters.

Those female voters are saying, "Sen. Clinton needs our support now more than ever if we're going to see this six-on-one to try to bring her down," Penn told those on the campaign call.
