By ANN SANNER, Associated Press Writer 13 minutes ago WASHINGTON - A top Hillary Rodham Clinton fundraiser threw her support behind Republican John McCain on Wednesday, saying he will lead the country in a centrist fashion and accusing the Democrats of becoming too extreme. ADVERTISEMENT "I believe that Barack Obama, with MoveOn.org and Nancy Pelosi and Howard Dean, has taken the Democratic Party — and they will continue to — too far to the left," Lynn Forester de Rothschild said. "I'm not comfortable there." Rothschild is also a member of the Democratic National Committee's Platform Committee. She said she would be stepping down from her position on the committee but will not switch political parties. Clinton spokeswoman Kathleen Strand said in an e-mail that the New York senator disagrees with Rothschild's decision to endorse McCain. "Senator Clinton has been criss-crossing the country and doing whatever she can to make the very clear case that the Obama-Biden ticket represents the new ideas and positive change we need right now, and the McCain-Palin ticket does not," Strand said in the e-mail. Rothschild said she was excited by the prospect of a woman being in the White House, even though she and Republican vice presidential nominee Sarah Palin disagree on issues. The Alaska governor opposes abortion except in the case of a threat to the mother's life. Rothschild said she supports abortion rights. "I believe that the McCain-Palin government will be a centrist government," Rothschild said. "It's not going to be an ideological government." Rothschild is a member of the DNC's Democrats Abroad chapter and splits her time living in London and New York. She was one of Clinton's top fundraisers, bringing in more than $100,000 for her presidential campaign. She built a multimillion-dollar telecommunications company before marrying international banker Sir Evelyn de Rothschild. Rothschild said she has not discussed her support for McCain with Clinton. "I'm sure she is not pleased with what I'm doing today," she said. "But you know what? I have to do what I believe in."
