Update, June 8, 2016, 8:17 a.m.: Hillary Clinton defeated Bernie Sanders in the Democrats' California primary and laid claim to her party's nomination. Sanders, who will meet Thursday with President Barack Obama, vowed to fight on.
Bernie Sanders left it all in California.
Even with rival Hillary Clinton on the precipice of securing the Democratic presidential nomination, Sanders burned through $2.2 million on advertising ahead of today’s California primary, according to data provided to the Center for Public Integrity by The Tracking Firm, a nonpartisan media tracking company.
Sanders’ spending eclipsed that of Clinton, who spent about $1.4 million on TV and radio advertising in California alone.
The competitive, delegate-rich California primary arrives hours after the Associated Press declared Clinton the presumptive nominee, meaning that she has earned enough delegates to clinch the nomination.
This count includes superdelegates: free agents — often party leaders — who vote for their favored candidate at July’s Democratic convention in Philadelphia.
Sanders’ ad flurry included about 2,800 TV ads targeting California voters in the weeks leading up to the primary, according to an analysis of data provided by Kantar Media/CMAG, a firm that monitors advertising on broadcast television and national — but not local — cable.
Clinton’s campaign aired nearly 3,000 ads in California during the same time frame.
Such a concerted effort in California makes sense: delegates there make up about one-fifth of the total 2,383 needed to secure the nomination.
