Berkeley, California is arguably the most liberal city in the U.S. Tourist shops sell t-shirts touting its identity as a leftist hub.  The city is overwhelmingly white and wealthy, with large Asian and small Black minority populations, a median household income over $100,000, and median home value of nearly $1.3 million. When we think of the liberal elite, we think of Berkeley. So when residents last week voted down a new fossil fuel tax, it came as a rude surprise to green activists across the country.
