Anthony Corrado, a campaign expert at Colby College, said that though the refunds announced by Clinton on Monday were "certainly significant," he doubted that the loss of $850,000 would "have a material effect" on the senator's campaign, which has raised more than $55 million so far. He predicted that Bill Clinton's upcoming fundraiser for his wife, aimed at expatriates in London, would replace the loss.
