Well, your explanation of what really happened with the car tax machinations is so complete and supported as to be well nigh impregnable.
Not that the CAGOP/Dufus Sundheim/Arnold enthusiasts won't try. After all, it's what they do. They can't help themselves.
I prefer the term basic civics.
Under California law there are only two classes of individuals who can unilaterally create, increase or eliminate a direct tax.
1) The electorate through a simple majority vote on an initiative.
2) The Legislature through a super-majority vote on legislation.
The Governor of California lacks the authority to create, increase, reduce or eliminate a direct tax without the written cooperation of the electorate or the legislature.
The usual suspects are well aware of the governor's limitations but persist in spreading their big lie.
