evidence: The campaign of Sen. Bernie Sanders (I-Vt.), for instance, distributed talking points that zeroed in on fundraising, saying "Pete Buttigieg is a favorite candidate of Wall Street and the health care industry." [...] Sanders' comments led us to wonder if Buttigieg really is the sweetheart of the health care industry. We asked the Sanders campaign for its evidence. Staffers pointed us to data from the Center for Responsive Politics, a nonprofit group that operates the website OpenSecrets.org and tracks money from individuals and political action committees donated to political candidates and members of Congress. The center analyzes Federal Election Commission data and sorts contributions by categories based on the economic sector from which they come. [...] We asked Weber if Sanders' talking point about Buttigieg is true. That "depends on what you mean by 'health care industry,'" Weber wrote in an email. OpenSecrets defines its health sector by contributions from PACs and individuals working in various health industries, he said, and "for our data, that’s our broadest definition of health care."
