When Adam B. Schiff recently brought his U.S. Senate campaign to Northern California, 500 people showed up for his stop at a 55-and-older community nestled in the green, rolling hills of the East Bay Area. Dozens more were turned away.
A few weeks earlier, Katie Porter drew a similar overflow crowd when she kicked off her bid to replace the retiring Sen. Dianne Feinstein with an appearance before the same Democratic audience.
The turnout suggests more than just keen interest in a primary that's still close to a year off. It reflects a notable shift in California politics.
