With California already facing huge deficits, they want to spend another $68 billion on a green project

The problem is that if this railroad line made sense, the government wouldn't have to subsidize it.  Florida, Ohio and Wisconsin may have thought that they were saving taxpayers' money by turning down the Federal grants, but the money is simply going to go to other projects, such as the one in California.  From the Associated Press:

In a narrow 21-16 party-line vote that involved intense lobbying by the governor, legislative leaders and labor groups, the state Senate approved the measure marking the launch of California's ambitious bullet train, which has spent years in the planning stages. . . .
The bill authorizes the state to begin selling $4.5 billion in voter-approved bonds that includes $2.6 billion to build an initial 130-mile stretch of the high-speed rail line in the agriculturally rich Central Valley. That allows the state to draw another $3.2 billion in federal funding.

The first segment of the line will run from Madera to Bakersfield.

Senate Republicans blasted the decision, citing the state's ongoing budget problems. They said project would push California over a fiscal cliff. No GOP senators voted for the bill Friday.

The final cost of the completed project from Los Angeles to San Francisco is projected to be $68 billion.

"It's unfortunate that the majority would rather spend billions of dollars that we don't have for a train to nowhere than keep schools open and harmless from budget cuts," Sen. Tom Harman, R-Huntington Beach, said in a statement. . . .
