Dissension in the Ranks.

If not now for Zev Yaroslavsky, then when?

The county supervisor has yet to declare whether he'll run for L.A. mayor. And while he has waited, several possible high-profile supporters have deserted him for the campaign of City Attorney James Hahn.

The latest was city commissioner Lisa Specht, who would not comment on her decision. But one politically connected observer who knows Specht said she had grown tired of waiting for a decision from Yaroslavsky, known in some circles as the Hamlet of L.A. politics.

"He's already gone through three deadlines by which he's told his friends and supporters he would have a decision," the source said. "With this race moving ahead so early, it's no wonder she looked elsewhere."
