I'm afraid that's wishful thinking. Davis will sign it (in fact he's already announced that he will) because vetoing it would totally p!ss of his liberal base. He's already having problems keeping liberal Democrats lined up behind him. Green Party candidate Peter Camejo is pulling about 5% at this time. Big-time liberals and environmentalists and Hollywood stars pushed heavily for AB 1493. They made it a make-or-break litmus issue for Democrats, who still had to resort to desperate subterfuges to pass it with the minimum 41 votes in the Assembly.
Davis is boxed in good on this one. He must and will sign it, but the consequences could cost him his re-election.
