I know there had been some doubt among the HSR deniers about Arnold's position, but as KQED's John Myers reports he is indeed endorsing Yes on 1A.
Arnold spoke at the Commonwealth Club last month and explained his support for high speed rail:
There is far more economic opportunity in fighting global warming than economic risk....We shouldn't let the budget crisis hold back good things for the future. 20 years from now you can't look back and say "well they had a budget crisis so we didn't do it." Just because we had a problem with the budget does not mean that people should vote "no" on high speed rail. Our rail system in America is so old, we're driving the same speed as 100 years ago, the same system as 100 years ago. We should modernize, we should do what other countries do...We should start in this state, we should show leadership.
It would be nice if he would actually get out and do some campaigning for it. That goes for the rest of you California political leaders.
