I suspect he failed mostly because he tried to get the legislature to adopt it after the initial budget-centered rollback (which was before recent changes to the budget process which made budget impasses of the type exploited to kill it initially unlikely), rather than using the initiative process. While money certainly effects the initiative process, it's usually a much better way to get something whose benefits are simple and easy to understand to the average person and broadly distributed but where there is entrenched narrow institutional opposition passed in California. It's not cheap, but it would be dirt simple to raise the money necessary to get this on the ballot and get a decent campaign for it. (Intuit/Norquist would still fight it, but convincing voters is different than convincing politicians.)
