Campaign filings show that the San Francisco 49ers spent nearly $5 million on their stadium referendum campaign in Santa Clara this spring, including a last-minute infusion of $800,000 from Niners owner Jed York. That would be a record for a Santa Clara referendum, and close to one for any stadium campaign anywhere. It would also be more than $300 per “yes” vote.
Meanwhile, the opposition, Santa Clara Plays Fair, raised a little over $20,000 for the “no” side. That means the 100-to-1 rule remains in place: Outspend your opposition by a factor of 100, and you’ll probably win a stadium vote; less than that, and you’ll probably lose.
