A key passage:
By the end of March, the self-described democratic socialist senator from Vermont had spent nearly $166 million on his campaign -- more than any other 2016 presidential contender, including rival Hillary Clinton. More than $91 million went to a small group of admakers and media buyers who produced a swarm of commercials and placed them on television, radio and online, according to a Washington Post analysis of Federal Election Commission reports.
Granted, Hillary Cliinton came very close: The Washington Post pegs her campaign spending at nearly $165 million. Read the full story here.
Secretary Clinton has vastly more support from PACs and advocacy groups, which have been spending heavily on TV and radio ads supporting her campaign, as an Ad Age Datacenter analysis of Kantar Media's Campaign Media Analysis Group (CMAG) data shows. Read that report, released today, here.
