virtually declared victory after forcing a moderate Republican out of a highly contested House race in upstate New York. The Republican candidate, Dede Scozzafava, withdrew Saturday virtually guaranteeing a win for Conservative Party Candidate Doug Hoffman in New York's 23rd Congressional district.

White House senior advisor Valerie Jarrett told ABC's George Stephanopolous that pressure on Scozzafava to drop out shows how conservatives are marginalizing moderates. "I think [the Republican Party is] becoming more and extreme and more and more marginalized," said Jarrett.
