My apologies for this considerably late reply. Not only did Davis vote against the party line on this vote, with the republicans as you stated, but he took heat for it. Gifford Miller "punished" the four dems who did not vote along party lines on this issue by removing them from committee appointments. Davis was a tough cookie though...he sued Miller. I don't know if the case ever got anywhere or not. If nothing else, it seems Davis was his own man not to be manipulated by the party machine.
We definitely do not want for our next mayor, or even our next councilmember from that district, this vengeful, spiteful, vain person, Gifford Miller, whose original first name is not originally Gifford but was changed in an attempt to sound classier.
