The federal government is LOANING $12 billion for the project. So far the project has an "estimated" cost of $280 billion. So California put up a bond measure to fund it. Problem is, how will they sell that many bonds? And... If they don't, and they start the project, there is no provision to fund it if the bond doesn't come up with the money, which it won't.
The woole thing is a scam by Jerry Brown and the union people to glom on to that $12 billion and spread it around amungst themselves, then the project will go bankrupt but the money will not get re-paid, so now the state has more debt.
Even the people on the inside of the project say it won't work.
Crooks every one.
