By Tuesday evening, Mr. Sanders had posted a video on Twitter addressing the ads. “The billionaire class is getting nervous, and they should.”The Sanders campaign, like many of its rivals, often points to signs of adversity to juice donations, and Mr. Sanders’s supporters responded on Tuesday with a flood of contributions. The financial windfall underscored a central challenge facing his opponents: Attacking him can help fuel his campaign. The attack ad, which will run through the caucuses on Monday, comes amid rising concern among some Democratic Party elected officials and strategists, who have grown increasingly anxious about the prospect that Mr. Sanders could capture the nomination. Several recent polls have shown him leading in Iowa and New Hampshire, the first two nominating contests.
