LOS ANGELES _ Bernie Sanders' campaign is expressing high confidence about a substantial victory in California, the Super Tuesday primary state that will serve as the ultimate test case for how far Michael Bloomberg's money can carry him in the Democratic presidential race.
With a whopping 415 delegates at stake, it's also the contest that may hand Sanders the insurmountable delegate lead his opponents are so worried about _ even if it takes days or weeks to realize due to a delayed count of mail-in ballots.
While Sanders has been intensely organizing since his 2016 primary loss here _ the campaign knocked on 1 million doors just last weekend_ the multi-billionaire Bloomberg has swarmed the airwaves in a matter of a few months, spending more than $75 million on local California TV and radio, according to ad tracking company Medium Buying. That's more than 10 times what Sanders has spent, and it doesn't even include the additional national and digital ad buys that permeate here.
