Rep. Michele Bachmann sent out a fundraising letter Thursday bashing Whoopi Goldberg, who criticized the Republican presidential hopeful on her television show this week for signing a pledge penned by a socially conservative group in Iowa.

“In order to show Whoopi we won’t stand for her attacks, I have set a goal to raise $40,000 in the next 24 hours,” Bachmann wrote in the e-mail, using a deadline-based technique she has employed often over the years to amass large amounts of money in individual contributions.

The pledge, called “The Marriage Vow,” asked signatories to endorse the notion that children are best raised by a mother and a father and to promise to oppose efforts to expand same-sex marriage. It condemned pornography and Sharia law. It also claimed that more black children were born to two-parent households under slavery than today — a passage that the group, the Family Leader, later retracted.

Goldberg and the regular panelists on her ABC show, “The View,” mocked the pledge as archaic and judgmental, with Elizabeth Hasselbeck, a conservative, predicting that it could sink Bachmann’s campaign.

Goldberg, a well-known liberal, was particularly agitated, saying Bachmann was entitled to her position on same sex marriage but that the slavery passage was racist and that “we’re not going back to the way it was, so get over yourself.” She added that people should “stop pointing the finger” at single parents.

Bachmann has said she did not endorse the slavery passage, which was in the preamble to the pledge. Bachmann, raised for part of her life by her divorced mother, said in the letter that Goldberg mischaracterized her views on single parents, and she tied the remarks to a broader attack on her campaign by Hollywood and the “liberal Democrat establishment.”

“The comments from Whoopi Goldberg have hit a new low, and I must have the resources to defend myself and fight back,” she wrote.

Bachmann, who has proved to be a successful fundraiser as a candidate for the House from Minnesota, is the only declared GOP candidate who has not offered the public a peek into her finances. That will change Friday, the deadline for candidates to submit their latest campaign finance reports to the Federal Elections Commission.

While she is experienced at raising money from individual donors who contribute small amounts, she is turning to experts to help draw some of the larger corporate donations typically needed to run a successful presidential campaign. Also Thursday, the campaign announced that it had finalized its senior staff, which includes two veteran finance directors.
