Call it the Big Gouge. Tuesday, Gov. Jerry Brown’s administration will try for a third time to secure a political mega-deal that would commit millions of California property owners to pay for the $19.9 billion  Delta twin-tunnels water grab. Without approval of voters or the Legislature. It’s an atrocious abuse of the political system that must be stopped. Blocking the effort would save property owners thousands of dollars over the next 20-40 years and help preserve the health of the Delta for the next generation and beyond.
