Here is a better idea, look at the law and use the power of government against them.
Look, I heard all these Cities and Counties have signed letters to Obama. Make them put money where their mouth is.
Look for any way to tax the bejesus out of the constituencies of the President and the Democrat Party.
Look at County Easements where power is transmitted over it to power the city of San Fransisco, Tax it. See that water that is pumped from the ground in the county for the city, tax it.
Here a tax, there a tax, every where a tax tax.
Use the power of government to nail them in everyway you can.
Truck the water in on trucks (great for global warming) with the money.
I bet they will turn on the water themselves and they will be begging for you to stop.
USE THE POWER!
The ire of the people is what has to rise here. Thousands of people, turning the water on and then standing vigil over it. Embarassment to no end...people from all over the country flocking to aid the farmers...just like they did in Klamath.
The pressure would build and build until they simply had to turn it around...or risk civil upheavel, with them being the object of everyone's ire as the fault.
We've already shown that can work in Klamath...some of them just have to make that move and then be supported by the others...and us.
