SACRAMENTO, Calif. (AP) — How much is one vote worth in the California state Senate?

A half-billion dollars, if linked to a gas-tax hike.

The key vote to raise Californians’ gas taxes and vehicle fees Thursday came from a little-known Republican lawmaker.

Sen. Anthony Cannella won a $400 million railroad extension into his Central Valley district in California’s agricultural heartland and $100 million for the University of California, Merced.

He was among several lawmakers who secured nearly $1 billion in transportation projects.

They say the promises won their votes to raise $54 billion for roads, bridges, and mass transit over 10 years.

The deal raises gas taxes by 12 cents a gallon while increasing diesel taxes and vehicle fees.

Cannella was the only Republican to support a plan criticized by his GOP colleagues.
