Mayor Jim Hahn is wasting no time swinging into campaign mode. He spoke up for expanding the LAPD on Warren Olney's Which Way, L.A.? Monday (audio here). On Tuesday he's set to call into McIntyre in the Morning on KABC at 7:40 a.m. (ahead of Carol Channing and Dennis Miller, and behind Robert Greenwald, producer of Outfoxed) and to appear on Airtalk with Larry Mantle on KPCC at 11:15 a.m. In between, Hahn is doing a 9 a.m. press conference at MacArthur Park to talk about a crackdown on fake IDs.

Also: For all we know, the contest for mayor will be settled in the San Fernando Valley again. Certainly, the Valley and its 40% or so of Los Angeles voters will get a lot of attention from candidates (two of them, Bob Hertzberg and Richard Alarcon, hail from over the hill). On Wednesday, the Valley Econcomic Alliance is holding an information summit on the state of the place. The key presentation will be from Joel Kotkin of the New America Foundation and Sci-Arc, in cooperation with a new Valley-based entity called the Mulholland Institute. The Economic Alliance started the institute this year as a kind of pro-Valley think tank.

* Tuesday morning update: Hahn and Hertzberg yesterday formally took out papers to run, as did Walter Moore and a new candidate, USC student Jeff Mitchell. [** The Times and the city clerk's website give the name as Mitchell Jackson, and also add another: Addie M. Miller.] They have to file their intent to run by Saturday and complete the paperwork by December 8. Also, although Prop. A got 64% of the vote in the city (two points short of passage), the Daily News editorializes today that Hahn didn't get some message about the people not wanting to pay higher taxes for more police.
