Schwarzenegger...it's the right thing to do (see Japan's and Europe's High Speed Rail Systems), but a lot of Oxen will be gored (i.e. Special Interests), so sadly this mess is the result.
If you have experienced the daily commute into and out of Silicon Valley from the Central Valley (where the only affordable housing exists) then you'd understand why voters keep supporting the project. The fact that the GOP is the legal arm of Corporate Special Interests, there will always be well-funded opposition to any projects that focus on the needs of the lower classes.
